Can anyone tell me in detail why the Moon is always facing the Earth? Thanks!

The Moon always faces the Earth in one way because the Moon's autobiographical and orbital periods are the same. (Day).

To understand this phenomenon, you can do an experiment. Draw a circle and mark the east-west-north-south direction. You stand in the center of the circle (representing the earth), find a friend, stand on the circle, have his face facing forward (i.e. without twisting his neck), move counterclockwise along the circle, and ask him to keep his face facing the center of the circle as he moves along the circle, which is you.

Then such a process basically simulates the rotation of the moon and the earth.

Obviously, in such a process, your friend is always facing you in the face. Here's an explanation of why, in such a process, the revolution period is equal to the rotation period.

Your friend starts from your due north, circles you, and when he appears due north again, he completes a revolution. (Similar to the time it takes for the Moon to revolve around the Earth.) ）

Let's take a look at what his rotation time is. We might as well set your friend's position when due north of you and face due south as the initial pose. Then we can see that when your friend moves counterclockwise to your due west position, his rotation posture rotates 90 degrees counterclockwise.

If your friend doesn't "rotate" in the process, then when he's in this position, he's not facing you, but still facing due south. In the actual experiment, your friend is facing due east in this position, so he rotates 90 degrees counterclockwise around himself relative to his initial position.

Similarly, when he walks due south of you, he autobiography 180 degrees relative to his initial posture. When he walks due east of you, he is autobiography 270 degrees relative to his initial posture. When he walks to your due north again, he is autobiographed 360 degrees relative to his initial posture.

That is, he completes a rotation cycle.

Because the completion of a revolution process is just the completion of a rotation process, so from the perspective of time, this rotation period is equal to the revolution period. Because throughout the process, your friend always faces you with his body face, that is, the moon always faces the earth with one side.

Hope it helps!

Because the speed of the Moon's autobiography is equal to the speed at which it revolves around the Earth.

It's like holding a ball tied to a chain in your hand, spinning in place, your hand is the earth, the ball is the moon, and the side of the ball chain is always facing you.

The moon is a ball, and there is no side, and the side that we see on Earth is because you're in the distance, just like you put a soccer ball in the distance, and you always see a side, and it's simple.

Because the period of the Moon's revolution around the Earth is the same as the period of the Moon's rotation.

Because you can see it when it's bright, and you can see it when it's dark!

1. The moon is self-**Because when the moon revolves around the earth, the moon itself will also rotate once, and the speed is basically the same, so we see that only one side of the moon is facing the earth;

2. Tidal action: the interaction between the moon's rotation and revolution makes the rotation speed closer to the rotation speed. The end result is that the rotation speed is the same as the revolution speed, which is a tidal locking phenomenon.

Tidal locking, also known as synchronous rotation, is a phenomenon in which a celestial body is permanently stable facing another object due to a gravitational gradient. The locked celestial body rotates once on its own axis, taking the same amount of time to make one revolution around its companion, and this synchronous rotation results in a hemisphere facing its partner in a fixed direction;

3. The Moon's own factors: the Moon can flow and move when it first forms, and then the Earth gradually cools and turns into rocks, which make the Moon an irregular sphere in the later evolution process;

4. The mass of the moon: because the mass of the earth is much larger than the mass of the moon, the gravitational pull of the earth will affect the speed of the moon's rotation and revolution, which will eventually cause the moon's rotation period to be the same as the revolution period. Both the Moon's rotation and revolution period are about four weeks, so whenever the Moon is viewed from the Earth, only the same hemisphere can be seen.

Nevertheless, due to balance motion and parallax, about 59% of the Moon's surface can be seen from repeated observations from Earth.

There are no secrets on the far side of the moon. Because the moon does not rotate, only one side faces the Earth during the rotation, and there will be a visual difference because of the different observations.

There are many craters on the far side of the moon, and the temperature on the far side of the moon is particularly low, because the speed of the moon's rotation and revolution are the same, so we can only see one side of the moon.

There are things that humans don't know, some solid water, caused by the rotation of the moon, and the rotation of the moon is very slow.
