What is the other name for the moon?

The moon is also known as Taiyin, Xuantu, Chanjuan and Yupan. It is a satellite of the earth and the fifth largest satellite in the solar system. The diameter of the moon is about one-fourth that of the Earth, and its mass is about one-eighty-one times that of the Earth. The moon is the most massive satellite, and its surface is covered with impact craters formed by the impacts of small celestial bodies. The average distance between the moon and the earth is about 380,000 kilometers, which is about 30 times the diameter of the earth.

Topography:

There are dark parts and bright areas on the moon's surface. The bright areas are highlands, and the dark areas are plains or basins, etc. The low-lying areas are called the Moon Land and the Moon Sea respectively. When early astronomers observed the moon, they thought that the dark areas were covered with sea water, so they called them "sea". The famous ones include the Sea of ??Clouds, the Sea of ??Shit, the Sea of ??Tranquility, etc. The bright part is the mountain range, where there are many mountains and mountains, and there are dotted craters everywhere, that is, impact craters, which are a kind of circular raised low-lying shape.

There are more than 33,000 impact craters on the moon with a diameter greater than 1,000 meters. Bailey Crater, located near the South Pole, has a diameter of 295 kilometers and can fit the entire Hainan Island into it. The deepest mountain is Newton Crater, which is 8,788 meters deep. In addition to impact craters, there are also ordinary mountains on the moon. High mountains and deep valleys appear one after another, creating a unique scenery.

The structure of the far side of the moon is quite different from that of the front side. The maria occupies a small area and has many impact craters. The terrain is rugged and undulating. The longest and shortest lunar radii are located on the far side. Some places are 4 kilometers longer than the average radius of the moon, and some places are 5 kilometers shorter (such as Van de Graaf Depression). No "mass tumors" were found on the back. The moon crust on the back side is thicker than the front side, with a maximum thickness of 150 kilometers, while the thickness of the moon crust on the front side is only about 60 kilometers.

Impact Crater

The name Impact Crater was given by Galileo Galilei. It is a prominent feature of the lunar surface, covering almost the entire lunar surface. The largest impact crater is Bailey Crater near Antarctica, with a diameter of 295 kilometers, a little larger than Hainan Island. A small crater may even be a crater of tens of centimeters. There are approximately 33,000 with a diameter of not less than 1,000 meters. It accounts for 7%-10% of the moon's surface area.
