Our planet is in constant motion. Together with the Sun, it moves in space around the center of the Galaxy. And she, in turn, moves in the Universe. But the rotation of the Earth around the Sun and its own axis plays the greatest importance for all living things. Without this movement, conditions on the planet would be unsuitable for supporting life.

solar system

According to scientists, the Earth as a planet in the solar system was formed more than 4.5 billion years ago. During this time, the distance from the luminary practically did not change. The speed of the planet's movement and the gravitational force of the Sun balanced its orbit. It's not perfectly round, but it's stable. If the gravity of the star had been stronger or the speed of the Earth had noticeably decreased, then it would have fallen into the Sun. Otherwise, sooner or later it would fly into space, ceasing to be part of the system.

The distance from the Sun to the Earth makes it possible to maintain optimal temperature on its surface. The atmosphere also plays an important role in this. As the Earth rotates around the Sun, the seasons change. Nature has adapted to such cycles. But if our planet were at a greater distance, the temperature on it would become negative. If it were closer, all the water would evaporate, since the thermometer would exceed the boiling point.

The path of a planet around a star is called an orbit. The trajectory of this flight is not perfectly circular. It has an ellipse. The maximum difference is 5 million km. The closest point of the orbit to the Sun is at a distance of 147 km. It's called perihelion. Its land passes in January. In July, the planet is at its maximum distance from the star. The greatest distance is 152 million km. This point is called aphelion.

The rotation of the Earth around its axis and the Sun ensures a corresponding change in daily patterns and annual periods.

For humans, the movement of the planet around the center of the system is imperceptible. This is because the mass of the Earth is enormous. Nevertheless, every second we fly about 30 km in space. This seems unrealistic, but these are the calculations. On average, it is believed that the Earth is located at a distance of about 150 million km from the Sun. It makes one full revolution around the star in 365 days. The distance traveled per year is almost a billion kilometers.

The exact distance that our planet travels in a year, moving around the star, is 942 million km. Together with her we move through space in an elliptical orbit at a speed of 107,000 km/hour. The direction of rotation is from west to east, that is, counterclockwise.

The planet does not complete a full revolution in exactly 365 days, as is commonly believed. In this case, about six more hours pass. But for the convenience of chronology, this time is taken into account in total for 4 years. As a result, one additional day “accumulates”; it is added in February. This year is considered a leap year.

The speed of rotation of the Earth around the Sun is not constant. It has deviations from the average value. This is due to the elliptical orbit. The difference between the values ​​is most pronounced at the perihelion and aphelion points and is 1 km/sec. These changes are invisible, since we and all the objects around us move in the same coordinate system.

Change of seasons

The Earth's rotation around the Sun and the tilt of the planet's axis make the seasons possible. This is less noticeable at the equator. But closer to the poles, the annual cyclicity is more pronounced. The northern and southern hemispheres of the planet are heated unevenly by the energy of the Sun.

Moving around the star, they pass four conventional orbital points. At the same time, alternately twice during the six-month cycle they find themselves further or closer to it (in December and June - the days of the solstices). Accordingly, in a place where the surface of the planet warms up better, the ambient temperature is higher. The period in such a territory is usually called summer. In the other hemisphere it is noticeably colder at this time - it is winter there.

After three months of such movement with a periodicity of six months, the planetary axis is positioned in such a way that both hemispheres are in the same conditions for heating. At this time (in March and September - the days of the equinox) the temperature regimes are approximately equal. Then, depending on the hemisphere, autumn and spring begin.

Earth's axis

Our planet is a rotating ball. Its movement is carried out around a conventional axis and occurs according to the principle of a top. By resting its base on the plane in an untwisted state, it will maintain balance. When the rotation speed weakens, the top falls.

The earth has no support. The planet is affected by the gravitational forces of the Sun, Moon and other objects of the system and the Universe. Nevertheless, it maintains a constant position in space. The speed of its rotation, obtained during the formation of the core, is sufficient to maintain relative equilibrium.

The earth's axis does not pass perpendicularly through the globe of the planet. It is inclined at an angle of 66°33´. The rotation of the Earth around its axis and the Sun makes possible the change of seasons. The planet would “tumble” in space if it did not have a strict orientation. There would be no talk of any constancy of environmental conditions and life processes on its surface.

Axial rotation of the Earth

The rotation of the Earth around the Sun (one revolution) occurs throughout the year. During the day it alternates between day and night. If you look at the Earth's North Pole from space, you can see how it rotates counterclockwise. It completes a full rotation in approximately 24 hours. This period is called a day.

The speed of rotation determines the speed of day and night. In one hour, the planet rotates approximately 15 degrees. The speed of rotation at different points on its surface is different. This is due to the fact that it has a spherical shape. At the equator, the linear speed is 1669 km/h, or 464 m/sec. Closer to the poles this figure decreases. At the thirtieth latitude, the linear speed will already be 1445 km/h (400 m/sec).

Due to its axial rotation, the planet has a somewhat compressed shape at the poles. This movement also “forces” moving objects (including air and water flows) to deviate from their original direction (Coriolis force). Another important consequence of this rotation is the ebb and flow of tides.

the change of night and day

A spherical object is only half illuminated by a single light source at a certain moment. In relation to our planet, in one part of it there will be daylight at this moment. The unlit part will be hidden from the Sun - it is night there. Axial rotation makes it possible to alternate these periods.

In addition to the light regime, the conditions for heating the surface of the planet with the energy of the luminary change. This cyclicality is important. The speed of change of light and thermal regimes is carried out relatively quickly. In 24 hours, the surface does not have time to either heat up excessively or cool down below the optimal level.

The rotation of the Earth around the Sun and its axis at a relatively constant speed is of decisive importance for the animal world. Without a constant orbit, the planet would not remain in the optimal heating zone. Without axial rotation, day and night would last for six months. Neither one nor the other would contribute to the origin and preservation of life.

Uneven rotation

Throughout its history, humanity has become accustomed to the fact that the change of day and night occurs constantly. This served as a kind of standard of time and a symbol of the uniformity of life processes. The period of rotation of the Earth around the Sun is influenced to a certain extent by the ellipse of the orbit and other planets in the system.

Another feature is the change in the length of the day. The Earth's axial rotation occurs unevenly. There are several main reasons. Seasonal variations associated with atmospheric dynamics and precipitation distribution are important. In addition, a tidal wave directed against the direction of the planet’s movement constantly slows it down. This figure is negligible (for 40 thousand years per 1 second). But over 1 billion years, under the influence of this, the length of the day increased by 7 hours (from 17 to 24).

The consequences of the Earth's rotation around the Sun and its axis are being studied. These studies are of great practical and scientific importance. They are used not only to accurately determine stellar coordinates, but also to identify patterns that can influence human life processes and natural phenomena in hydrometeorology and other areas.

Our planet is in constant motion, it rotates around the Sun and its own axis. The Earth's axis is an imaginary line drawn from the North to the South Pole (they remain motionless during rotation) at an angle of 66 0 33 ꞌ relative to the plane of the Earth. People cannot notice the moment of rotation, because all objects move in parallel, their speed is the same. It would look exactly the same as if we were sailing on a ship and did not notice the movement of objects and objects on it.

A full revolution around the axis is completed within one sidereal day, consisting of 23 hours 56 minutes and 4 seconds. During this period, first one or the other side of the planet turns towards the Sun, receiving different amounts of heat and light from it. In addition, the rotation of the Earth around its axis affects its shape (flattened poles are the result of the planet’s rotation around its axis) and the deviation when bodies move in the horizontal plane (rivers, currents and winds of the Southern Hemisphere deviate to the left, of the Northern Hemisphere to the right).

Linear and angular rotation speed

(Earth Rotation)

The linear speed of rotation of the Earth around its axis is 465 m/s or 1674 km/h in the equator zone; as you move away from it, the speed gradually slows down, at the North and South Poles it is zero. For example, for citizens of the equatorial city of Quito (the capital of Ecuador in South America), the rotation speed is exactly 465 m/s, and for Muscovites living at the 55th parallel north of the equator, it is 260 m/s (almost half as much) .

Every year, the speed of rotation around the axis decreases by 4 milliseconds, which is due to the influence of the Moon on the strength of sea and ocean tides. The Moon's gravity "pulls" the water in the opposite direction to the Earth's axial rotation, creating a slight frictional force that slows the rotation speed by 4 milliseconds. The speed of angular rotation remains the same everywhere, its value is 15 degrees per hour.

Why does day give way to night?

(The change of night and day)

The time for a complete revolution of the Earth around its axis is one sidereal day (23 hours 56 minutes 4 seconds), during this time period the side illuminated by the Sun is first “in the power” of the day, the shadow side is under the control of the night, and then vice versa.

If the Earth rotated differently and one side of it was constantly turned towards the Sun, then there would be a high temperature (up to 100 degrees Celsius) and all the water would evaporate; on the other side, on the contrary, frost would rage and the water would be under a thick layer of ice. Both the first and second conditions would be unacceptable for the development of life and the existence of the human species.

Why do the seasons change?

(Change of seasons on Earth)

Due to the fact that the axis is tilted relative to the earth's surface at a certain angle, its parts receive different amounts of heat and light at different times, which causes the change of seasons. According to the astronomical parameters necessary to determine the time of year, certain points in time are taken as reference points: for summer and winter these are the Solstice Days (June 21 and December 22), for spring and autumn - the Equinoxes (March 20 and September 23). From September to March, the Northern Hemisphere faces the Sun for less time and, accordingly, receives less heat and light, hello winter-winter, the Southern Hemisphere at this time receives a lot of heat and light, long live summer! 6 months pass and the Earth moves to the opposite point of its orbit and the Northern Hemisphere receives more heat and light, the days become longer, the Sun rises higher - summer comes.

If the Earth were located in relation to the Sun in an exclusively vertical position, then the seasons would not exist at all, because all points on the half illuminated by the Sun would receive the same and uniform amount of heat and light.

The yellowed pages of Galileo's Dialogues rustled quietly in the autumn wind. Three brothers sat on the veranda of the house, bowing their heads thoughtfully. It was sad. The four-day “conversation”, which is almost four hundred years old, has ended, a conversation about the two most important systems of the world - Ptolemaic and Copernican.

No matter how interesting a book is, it always comes to an end. But a book never dies, especially one like this. She remains to live in our memory, in our thoughts. And so, in order to revive the lost feeling for a while, the three brothers - and they were a mathematician, astronomer and linguist (as we will call them in the future) - themselves had a conversation or argument on some similar issue.

There were three participants in the “Dialogue”: Sagredo, Salviati and Simplicio, and there were just three brothers. A suitable topic of conversation was found that suited everyone. Namely, since Galileo proved that the Earth rotates, it is reasonable to ask the following question: “Why does the Earth rotate counterclockwise?” That's what they decided on.

The first to take the floor, as an older brother, was the Mathematician. He clarified that the direction of rotation is a relative characteristic. When viewed from the North Pole, the Earth rotates counterclockwise, and when viewed from the South Pole, it rotates clockwise. So the question doesn't make sense.

“That’s where you’re wrong,” objected the Astronomer, who is the middle brother. – The northern hemisphere of the Earth is considered the upper hemisphere, and is usually viewed from its side. It is not for nothing that globes with a fixed axis have the northern hemisphere at the top. Even we, astronomers, strict people, say: “above the plane of the ecliptic,” i.e. the plane of the Earth’s orbit when we mean a half-space from the northern hemisphere, and “under” when from the southern hemisphere. Although sailors call latitudes close not only to the North Pole but also to the South Pole high, and low latitudes are those close to the equator. True, the point here is rather that the absolute value of latitude increases as you move in both directions from the equator. But the very concept of high latitude arose in the northern hemisphere.

“Brother Astronomer is right,” confirmed the Linguist, the younger brother. – And although the childish assertion that the Earth has an up and down is a historical relic and a consequence of the birth of civilization in the northern hemisphere, it is accepted and more convenient. If you ask the question strictly, it sounds too cumbersome: “Why does the Earth, seen from the North Pole, rotate counterclockwise?”

“Okay, I’ll answer this question as well,” said the Mathematician, smiling slyly. “Just answer me first,” he tossed a coin and showed it to everyone, “why did it come up heads and not tails?” You see, the appearance of rotation clockwise or counterclockwise, as well as the appearance of heads or tails, are random and equally probable events.

“Well, you’re wrong here,” interrupted the Astronomer. – In the Solar System, counterclockwise rotation (as viewed from the North Pole of the ecliptic) is predominant, and therefore more probable. Therefore, we, astronomers, call this movement direct, although it is “against”, and clockwise movement is called reverse, although it is “for”. And physicists and mathematicians, apparently, therefore accepted the counterclockwise movement as the positive direction of rotation and detour. This is how everything that is possible moves: the surface of the Sun, planets in orbits and around their axis, satellites and rings around planets and around their axis, the asteroid belt. Only a few celestial bodies have a reverse motion: the couch potato Uranus, along with all its satellites, inclined its axis of rotation under the orbital plane by eight degrees; lazy Venus, which has the longest day of 243 Earth days; some outer satellites of the giant planets and several comets and asteroids. The predominance of direct motion in the Solar System is explained by the fact that the protoplanetary cloud from which it arose had such a direction of rotation. So the chance that the Earth would rotate clockwise is extremely small.

In response to this, the Mathematician, who knew how to make a model out of anything, pulled a bus ticket out of his pocket and asked:

– Do you know that the chance that the number of this ticket could have been exactly “847935” was one in a million and, nevertheless, as you can see, it turned out to be exactly that. And all because it makes no sense to look for the probability of an event after it has happened. In addition, it makes sense to talk about probability only for events that can be repeated, that can be reproduced or observed in large numbers, and there cannot be any patterns in one event. This is why, for example, it is impossible to talk about the temperature or pressure of a gas in a volume that includes only one or a few molecules. In addition, you claim that the direction of rotation of the Earth is determined by the direction of rotation of the protocloud, but, meanwhile, you forget that it is itself random. You could, for example, study the initial conditions when throwing a coin and calculate which side it will land on. This suggests that, in principle, the coin falling out is not a random event. But the point here is not that the result cannot be predicted, but that it is unpredictable without knowledge of the initial conditions, which are themselves random. Therefore, both directions of rotation for the Earth are equally probable. Now, I hope, you understand that there is no point in arguing,” the Mathematician finished with the air of a winner. - Am I right, Brother Linguist?

– Both of you are essentially right. Your dispute is about words and formulations. It all depends on what meaning you put into the question. Naturally, everyone sought and found a solution to the question in a meaning close to him: a mathematician searches through probabilities, an astronomer through cosmogony, and I will now give you a third interpretation. Since I am a linguist, I look for meaning, first of all, in the meaning of words. “His gaze fell on his watch. - That's who will judge us. When you hear about clockwise rotation, you imagine a specific direction, but I see the word “clock”. For me, “clockwise” is the direction that coincides with the clockwise direction of our clocks. The question arises, why did people choose the direction of the hour hand as the main direction, and not, say, the direction of rotation of the potter's wheel or the rotation of the minute hand? And in general, why did people make the hour hand rotate in the direction we know? I think this is no coincidence. The direction of movement of the hand in a mechanical watch was taken to be the direction of rotation of the pointer in the first watch created by man - in the sun. It was they who determined not only the type of modern mechanical watches and the speed of rotation of their hour hand (only it began to rotate twice as slow as the shadow and hand in some previous 24-hour dials), but also the general appearance of instruments with a circular scale and a pointer indicator. Only the movement of the hour hand-shadow in a sundial had a constant direction of rotation and could always be reproduced - that’s why people took it as a standard. Note that the shadow from the pillar, as is known, rotates clockwise - in the same direction in which the visible movement of the Sun across the sky occurs. But, as Galileo showed, in reality the Sun is motionless, and its apparent movement is caused by the rotation of the Earth in the opposite direction, i.e. exactly counterclockwise. Thus, it is clear that the Earth can only rotate counterclockwise, if by this we mean not a specific direction, but namely the direction of the hour hand-shadow in a sun or mechanical clock. If the Earth rotated in a different direction, then the clockwise movement would be different.

“Well, brother, you are strong,” said the Mathematician admiringly. - This is incredible. It turns out that if civilization arose in the southern hemisphere, it would find that on their side the Earth rotates counterclockwise. After all, their sun moves across the sky in the direction opposite to our movement, which means their hour hand would rotate in the opposite direction.

I became interested in the topic of what rotates clockwise and what rotates counterclockwise. Very often you can find in the world many things based on vortices, spirals, twists that have a right spin of rotation, that is, twisted according to the gimlet rule, the right hand rule, and the left spin of rotation.

Spin is the intrinsic angular momentum of a particle. In order not to complicate the note with theory, it is better to see it once. The slow waltz element is a right spin turn.

For many years, there has been a debate among astronomers about the direction in which spiral galaxies rotate. Do they rotate, dragging spiral branches behind them, i.e., twisting? Or do they rotate with the ends of the spiral branches forward, unwinding?

At present, however, it is becoming clear that observations confirm the hypothesis of TWISTING of the spiral arms during rotation. American physicist Michael Longo was able to confirm that most of the galaxies in the Universe are oriented to the right (right-hand spin), i.e. rotates clockwise when viewed from its north pole.

The solar system rotates counterclockwise: all planets, asteroids, and comets rotate in the same direction (counterclockwise when viewed from the north pole of the world). The Sun rotates around its axis counterclockwise when viewed from the north pole of the ecliptic. And the Earth (like all the planets of the solar system, except Venus and Uranus) rotates around its axis counterclockwise.

The mass of Uranus, sandwiched between the mass of Saturn and the mass of Neptune, under the influence of the rotational moment of the mass of Saturn, received a clockwise rotation. Such an impact from Saturn could occur due to the fact that the mass of Saturn is 5.5 times the mass of Neptune.

Venus rotates in the opposite direction than almost all planets. The mass of the planet Earth spun the mass of the planet Venus, which received a clockwise rotation. Therefore, the daily rotation periods of the planets Earth and Venus should also be close to each other.

What else is spinning and spinning?

The snail's house spins clockwise from the center (that is, the rotation here occurs with a left spin turn, counterclockwise).

Tornadoes and hurricanes (winds centered in the cyclone area) blow counterclockwise in the Northern Hemisphere and are subject to centripetal force, while winds centered in the anticyclone area blow clockwise and have centrifugal force. (In the Southern Hemisphere, everything is exactly the opposite.)

The DNA molecule is twisted into a right-handed double helix. This is because the backbone of the DNA double helix is ​​made entirely of right-handed deoxyribose sugar molecules. Interestingly, during cloning, some nucleic acids change the direction of twist of their helices from right to left. On the contrary, all amino acids are twisted counterclockwise, to the left.

Flocks of bats, flying out of caves, usually form a “right-handed” vortex. But in the caves near Karlovy Vary (Czech Republic), for some reason they are circling in a counterclockwise spiral...

One cat’s tail spins clockwise when it sees sparrows (these are her favorite birds), and if they are not sparrows, but other birds, then it spins counterclockwise.

And if we take Humanity, then we see that all sporting events take place counterclockwise (auto racing, horse racing, running in a stadium, etc.) After some centuries, athletes noticed that it is much more convenient to run this way. Running counterclockwise across the stadium, the athlete takes a wider step with his right foot than he would with his left, since the range of motion of the right leg is several centimeters greater. In most armies of the world, turning in a circle is carried out through the left shoulder, that is, counterclockwise; church rituals; traffic on roads in most countries of the world, with the exception of Great Britain, Japan and some others; at school the letters “o”, “a”, “b”, etc. - from the first grade they are taught to write counterclockwise. Subsequently, the overwhelming majority of the adult population draws a circle and stirs the sugar in the mug with a spoon counterclockwise.

And what follows from all this? Question: Is it natural for humans to rotate counterclockwise?

As a conclusion: the Universe moves clockwise, but the solar system moves against it, the physical development of all living things goes clockwise, consciousness moves against it.

For an observer located in the Northern Hemisphere, for example, in the European part of Russia, the Sun usually rises in the east and rises to the south, occupying the highest position in the sky at noon, then slopes to the west and disappears behind the horizon. This movement of the Sun is only visible and is caused by the rotation of the Earth around its axis. If you look at the Earth from above in the direction of the North Pole, it will rotate counterclockwise. At the same time, the Sun is in place, the appearance of its movement is created due to the rotation of the Earth.

Annual rotation of the Earth

The Earth also rotates counterclockwise around the Sun: if you look at the planet from above, from the North Pole. Because the Earth's axis is tilted relative to its plane of rotation, it illuminates it unevenly as the Earth rotates around the Sun. Some areas receive more sunlight, others less. Thanks to this, the seasons change and the length of the day changes.

Spring and autumn equinox

Twice a year, on March 21 and September 23, the Sun illuminates the Northern and Southern Hemispheres equally. These moments are known as the autumn equinox. In March, autumn begins in the Northern Hemisphere, and autumn in the Southern Hemisphere. In September, on the contrary, autumn comes to the Northern Hemisphere, and spring to the Southern Hemisphere.

Summer and winter solstice

In the Northern Hemisphere, on June 22, the Sun rises highest above the horizon. The day has the longest duration, and the night on this day is the shortest. The winter solstice occurs on December 22 - the day has the shortest duration and the night has the longest. In the Southern Hemisphere, the opposite happens.

polar night

Due to the tilt of the earth's axis, the polar and subpolar regions of the Northern Hemisphere are without sunlight during the winter months - the Sun does not rise above the horizon at all. This phenomenon is known as the polar night. A similar polar night exists for the circumpolar regions of the Southern Hemisphere, the difference between them is exactly six months.

What gives the Earth its rotation around the Sun

Planets cannot help but revolve around their stars - otherwise they would simply be attracted and burnt up. The uniqueness of the Earth lies in the fact that its axis tilt of 23.44° turned out to be optimal for the emergence of all the diversity of life on the planet.

It is thanks to the tilt of the axis that the seasons change, there are different climatic zones that provide the diversity of the earth's flora and fauna. Changes in the heating of the earth's surface ensure the movement of air masses, which means precipitation in the form of rain and snow.

The distance from the Earth to the Sun of 149,600,000 km also turned out to be optimal. A little further, and water on Earth would only be in the form of ice. Any closer and the temperature would have been too high. The very emergence of life on Earth and the diversity of its forms became possible precisely thanks to the unique coincidence of so many factors.

Man sees the Earth as flat, but it has long been established that the Earth is a ball. People agreed to call this celestial body a planet. Where did this name come from?

Ancient Greek astronomers, who observed the behavior of celestial bodies, introduced two terms with opposite meanings: planetes asteres - “stars” - celestial bodies similar to stars, moving throughout; asteres aplanis - “fixed stars” - celestial bodies that remained motionless throughout the year. In the beliefs of the Greeks, the Earth was motionless and located in the center, so they classified it as a “fixed star”. The Greeks knew Mercury, Venus, Mars, Jupiter and Saturn, visible to the naked eye, but they called them not “planets”, but “wandering”. In Ancient Rome, astronomers already called these bodies “planets”, adding to this the Sun and the Moon. The idea of ​​a seven-planet system survived until the Middle Ages. In the 16th century, Nicolaus Copernicus changed his views on the device, noticing its heliocentricity. The Earth, previously considered the center of the world, was reduced to the position of one of the planets revolving around the Sun. In 1543, Copernicus published his work entitled “On the Revolutions of the Celestial Spheres,” in which he expressed his point of view. Unfortunately, the church did not appreciate the revolutionary nature of Copernicus’s views: his sad fate is known. By the way, according to Engels, the “liberation of natural science from theology” begins its chronology precisely with the published work of Copernicus. So, Copernicus replaced the geocentric system of the world with a heliocentric one. The name “planet” has stuck with the Earth. The definition of a planet, in general, has always been ambiguous. Some astronomers argue that the planet must be quite massive, while others consider this an optional condition. If we approach the issue formally, the Earth can be safely called a planet, if only because the word “planet” itself comes from the ancient Greek planis, meaning “movable,” and modern science has no doubt about the mobility of the Earth.

“And yet, she spins!” – we have known this encyclopedic phrase, uttered by the physicist and astronomer of the past Galileo Galilei, since our school days. But why does the Earth rotate? In fact, this question is often asked by their parents as young children, and adults themselves are not averse to understanding the secrets of the Earth’s rotation.

For the first time, an Italian scientist spoke about the fact that the Earth rotates around its axis in his scientific works at the beginning of the 16th century. But there has always been a lot of controversy in the scientific community about what rotation occurs. One of the most common theories says that in the process of the earth’s rotation, other processes played a major role - those that took place in time immemorial, when only education. Clouds of cosmic dust “came together”, and thus the “embryos” of planets were formed. Then other cosmic bodies – large and smaller – were “attracted”. It is precisely collisions with large celestial ones, according to a number of scientists, that determine the constant rotation of the planets. And then, according to the theory, they continued to rotate by inertia. True, if we take this theory into account, many natural questions arise. Why are there six planets in the solar system that rotate in one direction, and another one, Venus, in the opposite direction? Why does the planet Uranus rotate in such a way that there is no change in time of day on this planet? Why can the speed of rotation of the earth change (slightly, of course, but still)? Scientists have yet to answer all these questions. It is known that the Earth tends to slow down its rotation somewhat. Every century, the time for a complete rotation around an axis increases by approximately 0.0024 seconds. Scientists attribute this to the influence of the Earth's satellite, the Moon. Well, about the planets of the solar system, we can say that the planet Venus is considered the “slowest” in terms of rotation, and Uranus is the fastest.
