Why is Venus s autobiography slow? Why is Venus s rotation so slow?

Starting from the assumption of the inhomogeneity of the radial distribution of interplanetary matter in the gravitational field of the sun, the influence of interplanetary matter on the rotation of terrestrial planets is deduced and calculated. The results show that Venus can have a typical state of rapid forward rotation in the early stage of formation, with continuous slowing of rotation under the action of interplanetary matter, and after about 109 yr of formation, the rotation is reversed and gradually tends to stabilize. The results of the calculations for other terrestrial planets are also reasonable, and the slow rotation of Mercury is more naturally explained.

The latest results of the Venus space probe on the gravitational field of Venus, the influence on the evolution of Venus's rotation caused by the asymmetry of the Venusian gravitational field. The results show that the rotation rate of Venus has a periodic variation as follows: · = According to the mechanical properties of the model of the internal composition of Venus, the permanent deformation of Venus caused by the above equation is calculated, resulting in the change of its moment of inertia on the axis of rotation.

According to the conclusion of [1], Venus is a rapidly rotating celestial body at the beginning of its formation, and the long-term slowdown of its rotation rate can be obtained by taking its average initial rotation period t0 15 hours: · g = radians seconds 2. If the gravitational field of Venus does not change much after its formation, then it can be seen from the results of Figure 1 that g played a role in the change of the rotation rate of Venus in the early days.

The astronomical community estimates that Venus may have been hit by another medium-sized celestial body at the beginning of its formation, and the force of the impact caused the rotation of Venus to turn into a slow rotation in the opposite direction, so it became what we see today.

This is still unknown, but it is generally believed that Venus was hit by a massive object in the early days of its formation. Venus is getting older than the day, and the Earth is of interest to many.

This is still unknown, but there is a conjecture that it may have been hit by a large star in the early stages of formation, and its proximity to the Sun is unreliable, because Mercury, which is closer, is much faster than Venus.

It should be related to lubricating oil, and now it is better to use industrial lubricants such as Great Wall and Uni-President. It's still not very scientific to use it for large machines like Venus.

Among the eight planets in the solar system, the fastest rotation is Jupiter, the largest head. The rotation takes only 9 hours, 50 minutes and 03 seconds. Saturn, the second fastest and second largest, takes a little over ten and a half hours to make one revolution.

The larger Uranus and Neptune also only take about 17 and 16 hours to make one revolution, respectively. The two smallest planets, Mercury, make one orbit, but they need one Earth day. Venus is longer, taking 243 Earth days to make one rotation.

So why do massive planets like Jupiter and Saturn rotate so fast? A popular saying is that it is because they are of relatively large mass. So the gravitational pull is comparatively larger.

The gravitational field is also relatively large. Then they can absorb more interstellar matter. And because the gravitational radius is comparatively far.

Celestial bodies such as asteroids and comets, when they hit them, they have enough distance to accelerate. Therefore, the speed of the impact will be very fast. When the planet has received a large number of celestial impacts.

Its rotation speed is also very fast.

Neither Mercury nor Venus has moons. And because they are closer to the sun, they are more likely to form a tidal lock with the sun. Although they are not yet completely tidally locked by the sun.

But it must be greatly affected by the gravitational pull of the sun. If they're completely tidal locked. Then their revolution and rotation periods will be exactly the same.

In addition, although today's Venus is indeed uninhabitable, some scientists speculate that the former Venus may be the same as the Earth, and there is life, but it may be because of some special reasons that Venus has become what it is today.

Because there are atmospheric waves on the surface of Venus, and this atmospheric wave will affect the rotation speed of Venus, and some activities inside the planet also have a certain impact on the rotation speed of Venus.

Because the winds on Venus are relatively strong, these winds will slightly affect the rotation speed of Venus.

The formation of atmospheric waves on Venus causes fluctuations in atmospheric pressure. This actually changes the speed of Venus' rotation, depending on the time of day.

Because volcanic eruptions on Venus emit large amounts of sulfur-containing gas, the solar wind cannot strip it all away. The thick atmosphere of Venus is also related to the weather changes on Venus, and it is difficult for scientists to find out why, because dust storms on Venus can blow all the magma on the surface of Venus into the atmosphere. The air pressure on Venus is very high and 80 times that of the earth, and the gas density is extremely high, and the solar wind can only strip off some of the high-altitude bodies, and it is difficult to peel off tens of kilometers close to the ground!

That's right, if its atmosphere were thinner, then the air pressure would not be so great, and the temperature difference would be smaller.

The thickness of the atmosphere is not necessarily related to the strength of the magnetic field, nor is it related to whether the solar wind can strip away the atmosphere. Venus has a very slow rotation and basically no magnetic field, and the reason why the atmosphere of Venus is still so thick is because the atmospheric pressure of Venus is 90 times that of the Earth, and the high pressure means that the atmosphere is bound to the atmosphere and it is difficult for the atmosphere to escape. The reason why the atmospheric pressure of Venus is higher than its rotation is slower than that of the Earth, 1 243, just like a washing machine to dry clothes, the slower the rotation and the smaller the centrifugal force, the less easy it is to throw out the clothes and water, and for Venus, the more difficult it is to throw out the atmosphere, so the atmosphere of Venus is thicker and the resulting temperature is also very high.

In physics, when a charged body rotates, a magnetic field will be formed around it, and the greater the rotation speed, the stronger the magnetic field, while a celestial body is rarely electrically neutral, so if a celestial body has a strong magnetic field, then its rotation speed must be very large.

Neutron stars are one such example.

Neutron stars are one of the endings of the death of stars, which can be referred to the content of the encyclopedia.

There are many factors that determine the speed of a planet's rotation, but it is mainly related to the gravitational force of the moon.

In the early days, the rotation speed of the earth was much greater than today, but the gravitational pull of the moon induced tidal motion and solid tides on the earth, which consumed the energy of the earth's rotation, so the rotation speed has been much slower today and will continue to slow down in the future.

Interestingly, the Earth's gravitational pull on the Moon also caused a solid tide on the Moon to slow down the Moon's rotation, so that the Moon's rotation eventually coincided with its rotation around the Earth, always facing the Earth on the same side.

Large planets like Saturn and Jupiter have relatively small gravitational forces on their moons, so they rotate faster.

There is also Venus, whose rotation is slower than its orbital motion around the Sun, and it is retrograde. This may be the result of another large asteroid colliding with it in history.

The rotation period of the planets is determined by chance at the time of birth, but it is not impossible, for example, the rotation period of the Earth was only 4 hours at the beginning, but then it became slower and slower due to the tidal brakes of the Moon. Venus has no moons and no tidal brakes, but there is a theory that Venus rotated relatively fast in the early days, at least faster than it is now, but later it was hit by a large celestial body in the tangential direction, causing the rotation to not only slow down, but also reverse. Venus is also the only planet in the solar system that rotates in the opposite direction.

Mercury's rotation period (59 days) is less than its orbital period (88 days). Because Mercury is too close to the Sun, it is pulled by the Sun's gravitational pull for a long time, which shifts the center of mass of Mercury, causing Mercury's rotation period and orbital period to tend to be equal. In a few years, Mercury will face the Sun on only one side, just like the Moon.

This phenomenon is relatively common in the moons of large planets.

There are many conjectures, and the more popular one is that Venus was hit by a massive object (such as an asteroid) in the early stage of its formation, forcing it to change its rotation direction, but there are also many problems with this explanation.

Any object can emit radio waves. This wave is located farther out of the spectrum than infrared rays, and the hotter the object, the more radio waves it emits and the greater the energy. Radio waves can penetrate clouds to help people depict the surface of Venus more scientifically and measure its rotation speed.

According to the results, Venus rotates unusually slowly, and one rotation of Venus is equivalent to 243 on Earth

day, and produce a "mistake" in the direction, not from west to east, but from east to west. It has not been possible to explain this phenomenon so far, and can only speculate on the basis of hypotheses or the results of current research.

One explanation or conjecture is that according to the "nebula hypothesis", nebulae can slowly shrink and gather together by their own strength, and slowly begin to rotate, the nebula is shrinking, its rotation speed is getting faster and faster, the central part forms a star, the peripheral part forms a planet, and finally the sun is formed in the remaining part of the central area, and the angular momentum of the sun is transferred to the planet by electromagnetic action, and the reason why the planets have a rotational inclination may come from their collision with small stars. When a planet is hit by a collision in one direction that is greater than a collision in another, a tilt in that direction is generated, resulting in a tilt of the axis of rotation. According to the orbital inclination of Venus only.

It is speculated that Venus is formed with less collision force and less rotational velocity, so Venus has a long rotation period.

Another explanation, or conjecture, is based on the "law of black holes" (conjecture because no proof of the "law of black holes" has been found). In the absence of an external force that matches the spin motion of the object in a constant and accurate manner, the object itself can make a constant and regular spin motion. According to natural phenomena, it is believed that there is a corresponding magnitude of black body in the center of the object.

This system in which the black body and the cosmic synchronous field form the spin of matter is called the law of black holes. In other words, the power source of Venus's rotation comes from the blackbody radiation inside Venus or the correlation between the increase of blackbody entropy inside Venus and the cosmic synchronous field. Because Venus's blackbody is less synchronized with the cosmic synchronous field, and the spin system of matter is weaker than that of other planets in the solar system, Venus has a long rotation period.
