Why doesn t the Moon always face the Earth when it doesn t tell itself?

The period of rotation of the Moon is equal to the period of revolution.

Yes, it's the same as the autobiography time and revolution time, Pluto and the card are also in this relationship, it seems that it is not a coincidence, there will be some kind of force after a long time, you imagine two balls, the big ball and the small ball are connected to a rigid long rod, the big ball is rotating, the small ball is rotating, in this case can not be considered that the small ball revolves around the big ball, and it is always facing the big ball, on the contrary, if the two cycles are different, then all the moon will leak out!

The Moon takes 27 days, 7 hours, 43 minutes and 11 seconds to make one revolution around the Earth in its orbit, and the Moon itself happens to rotate once (rotation) during this time. That is, the time it takes for the Moon to revolve around the Earth is equal to the time it takes to rotate. So the moon always has only one side facing the earth.

The rotation period is equal to the revolution period, of course, the reason why you don't understand it is the reference frame, and you should choose the star as the reference frame.

It is because the Earth and the Moon are both too massive (relative) and too close together to create a phenomenon called "tidal locking", so they will always face the Earth with one side.

Scientists also have studied this problem! The moon is facing the earth at all times, and scientists have reported an article that you can't help but watch in, which is very interesting. The signs show that the moon is hollow, probably an artificial satellite, a base for aliens from a long time ago, inhabited by aliens, and the back side is ,...... their rangeIf you search for the Moon, it's an alien masterpiece and you should be able to find it.

This is a very precise coincidence. It's like a geostationary Earth satellite. It's obviously going around. It seems to be still.

You can think of it this way: if you take the center of the earth out of it, and then you look at the motion of the moon from the whole solar system, then you agree that the moon is indeed rotating. If it helps you understand, please scatter some to me, thank you!

The Moon is deflected outward by centrifugal force when it revolves, but the center of gravity is deflected 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 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 Moon actually revolves on its own axis relative to the Earth. Therefore, whether the Moon rotates relative to the Earth or the Stars as a reference, the Moon rotates relative to the Earth. The Moon rotates while revolving around the Earth, with a period of days, which happens to be a sidereal month.

The Moon is a satellite belonging to the Earth's satellite system and is the only satellite on our Earth. Like the moons of other large planets, the Moon also has a revolution phenomenon, which is a natural law, and any satellite object is no exception. The movement of the Moon around the Earth does not always face the Earth.

It is not correct to say that the moon is always facing the earth. This may be the illusion that the lunar surface environment and reflectance are the same.

Because the surface of the moon is the same environment and reflectivity, no matter how the moon rotates and revolves, it will have the same visual response and no different changes. So when viewed from the earth, it looks like the illusion of always facing the earth. In fact, this statement is an original error.

The Moon is about 380,000 kilometers away from our Earth, making it the brightest object we can see in the night sky.

Whether it is the story of Chang'e flying to the moon or the laurel jade rabbit; Whether it is Su Shi's "When is the bright moon, ask for wine from the sky" or Zhang Yu's interpretation of "I admit that it is the moon's fault, the moonlight is too beautiful, you are too gentle" and so on, all add a mysterious color to the moon in the sky. As for the moon, it is also the material of ancient poets, leaving many popular verses, and people today do not see the ancient moon, but this month was like the ancients.

The bright moon in the Qin period, the bright moon in the Han period, and the tidal changes of the earth are mutual, which means that the earth can also make the moon tidal change, although there is seawater on the moon, but there is molten slurry on the moon in the early days, so the earth can make the moon tidal changes to achieve the purpose of slowing down the moon. There are rocks on the moon. Under the influence of the Earth's gravity, these things change the shape of the Moon, allowing it to slowly turn into an ellipse.

As a satellite of the earth, the moon has accompanied our earth for billions of years, why does the earth have such a large moon to accompany it? There are currently some theories that shortly after the formation of the solar system, a protoplanet the size of Mars collided with our Earth and eventually created a moon. The possibility exists.

On the one hand, in the early days of the solar system, the solar system was chaotic, with all kinds of celestial bodies and debris, and even some planetary embryos.

Because of the tidal locking phenomenon and the fact that the moon has the same rotation and rotation period, the moon can of course rotate.

Since the side of the Moon towards our Earth does not change, the Moon as seen on our Earth does not seem to rotate. In fact, the moon has been rotating and revolving, but because of the omission of its rotation, the return of the ball so we see the lunar chain dust as if it does not rotate.

Because the rotation speed of the earth is the same as the rotation speed of the moon, it seems that the ruler socks have not changed, but in fact, the moon is also rotating, but the rotation is too small.

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 lead to the moon's rotation period being the same as the revolution period.

We only see one side of the moon, because when the moon is orbiting the earth, the earth is also just autobiography, so we can only see one side of the moon, if the moon does not autobiography, then when the moon revolves around us we can see the whole picture of the moon.

If the Moon were twice as fast as it is now, we would be able to see the Moon in its entirety in less than one circle, as is the case with most planets in the solar system, and the Moon's autobiography is consistent with the Moon's revolution, but it wasn't like that in the beginning.

How the Moon revolves around the Earth

At close distances, the gravitational pull of the Earth turns the Moon into an ellipse, and the protruding side faces the Earth, because the Autobiography and Revolution of the Moon are not the same, so the line between the two will deviate, but because the gravitational pull of the Earth affects the rotation speed of the Moon.

If the Moon rotates one more time after one revolution, then the Earth pair will only exert force in the opposite direction of the Moon to ease the speed of the Moon's rotation, and if the Moon rotates one less time after one revolution, then the Earth will speed up its rotation in the direction of the Moon's rotation, so that we can only see one side of the Moon.
