What is the detailed information about the moon?

The moon is the common name of the moon, also called lunar. The moon is also about 4.6 billion years old, which is closely related to the earth. The moon also has a layered structure such as shell, mantle and core. The average thickness of the outermost lunar shell is about 60-65 kilometers. Below the lunar crust 1000 km is the lunar mantle, which occupies most of the volume of the moon. Below the moon mantle is the moon nucleus, the temperature of which is about 1000 degrees, and it is likely to be in a molten state. The moon is about 3476 kilometers in diameter, which is 3/ 1 1 of the earth. Its volume is only 1/49 of the earth's, and its mass is about 735 billion tons, which is equivalent to 1/8 1 of the earth's mass. The gravity on the surface of the moon is almost equal to 1/6 of the gravity of the earth.

There are dark parts and bright areas on the moon. When early astronomers observed the moon, they thought that dark areas were covered by seawater, so they were called "oceans". Famous are the sea of clouds, the wet sea and the sea of tranquility. The bright part is the mountains, which are staggered and dotted with craters. Bailey Crater is located near the South Pole, with a diameter of 295 kilometers, which can accommodate the whole Hainan Island. The deepest mountain is Newton crater, which is 8788 meters deep. Besides craters, there are ordinary mountains on the moon. Mountains and valleys overlap, giving you a unique vision.

The front of the moon always faces the earth. On the other hand, most of the back of the moon can't be seen from the earth, except the area near the edge of the moon, which can be seen occasionally due to the movement of Libra. In the era without detectors, the back of the moon has always been an unknown world.

One of the characteristics of the back of the moon is that it has almost no dark moon surface characteristics like the moon sea. When the probe runs to the back of the moon, it will not be able to communicate directly with the earth.
