Does the moon rotate? Will the moon rotate on its own?

Of course, and the rotation period of the Moon is the same as the rotation period, which is about 27 days, so we can only see one side of the Moon on Earth and not the other.

Yes

When the moon rotates, the center of gravity deviates outward under the action of centrifugal force, but the center of gravity shifts inward under the gravitational force of the earth. The Moon completes its rotation around its own axis under the action of these two forces. The Moon actually revolves on its own axis relative to the Earth.

Therefore, whether the Earth is used as a reference or a star as a reference, the Moon rotates relative to the Earth. The Moon rotates while revolving around the Earth, and the period day is exactly one sidereal month.

1. Yes. The rotation of the moon is only viewed from the perspective of taking the center of the moon as a frame of reference, which is essentially the relative motion of the moon to the center of the earth. And under this frame of reference, the center of the earth is stationary, and there is no rotation of the moon.

To sum up, the so-called rotation of the moon (to the center of the moon frame of reference) and the revolution of the moon (to the center of the earth frame of reference) are essentially the names of the same motion in different frames of reference.

2. The moon rotates while revolving around the earth, and the period day is exactly a sidereal month, so we can't see the far side of the moon. This phenomenon is called "synchronous rotation", and it is almost a universal law in the satellite world. It is thought to be the result of the long-term tidal action of the planets on the satellites.

The balance movement is a wonderful phenomenon that allows us to see 59% of the surface of the moon. There are mainly the following reasons:

1) In different parts of the elliptical orbit, the rotation speed does not match the angular velocity of the revolution.

2) The intersection of the white and equator.

It is precisely because of the rotation of the Moon, and the rotation period is the same as its rotation period around the Earth, that the phenomenon of "the Moon always faces the Earth with only one side", that is, there is a surface on the Moon that is not visible to people on the Earth (the so-called "back of the moon").

The Moon is a planet and is a satellite of the Earth. The Earth revolves around the Sun and the Moon revolves around the Earth. At the same time, they themselves are spinning.

It is precisely because the moon is constantly rotating that there are various moon phases that we see. For example, the moth crescent moon, the new moon, the full moon, and so on.

It won't turn straight because it has no gravity!

The rotation of the Moon is equal to the period of revolution (known as tidal locking), so the Moon always faces the Earth on the same side. The Earth's ocean tides arise mainly due to the gravitational pull of the Moon.

The moon always faces only one Earth, so the front and back sides are defined, the side facing the Earth is defined as the front of the Moon, and the side facing away from the Earth is the back side of the Moon. Because the Earth is large and the Moon is small, when you look at the Moon from the Earth, you can see about 59% of the surface of the Moon, and the rest is impossible to observe directly from the Earth.

It is not uncommon in the solar system for the Moon to have only one face facing the Earth, and this phenomenon is called tidal locking, and the Moon is tidally locked by the Earth, so that only one of the Moon faces the Earth. A tidally locked Moon does not have no rotation, and it takes the same amount of time for a planet to rotate once it is tidally locked as it does for one revolution, as shown in the figure below. It is for this reason that the Moon can do it with only one face facing the Earth.

If the Moon does not rotate, then the Moon will always have only one position facing the depths of the universe. As it orbits the Earth, its surface is gradually exposed to the Earth, and the full surface of the Moon can be seen from the Earth.

If the Moon's rotation period and revolution period were not equal, then the Moon would not have only one facing the Earth. Just as the earth revolves around the sun, the rotation period of the earth and the revolution period of the earth are not equal, so the sunlight can be sprinkled to various positions on the earth's surface, and if the sun also has a pair of eyes, the earth's surface can be seen under the sun's gaze.

When it comes to the sun, let's talk about the places that are easily misunderstood. Although only one of the Moon faces the Earth, the Moon is not tidally locked by the Sun, so both the front and back sides of the Moon can receive sunlight. When the moon is a large disc seen during the Lantern Festival, the sun's rays shine on the front side of the moon, and the back side of the moon is night at this time.

When the big year three. 10. On the first day of the new year, the moon cannot be seen from the sky because the sun's rays are sprinkled on the back side of the moon, and the front side of the moon has no light, so it cannot be seen on the earth.

Yes, the Moon not only revolves around the Earth, but also rotates constantly.
