Why is the moon so low?

The moon is a sphere, and its orbit around the earth is elliptical, so the distance between the moon and the earth is not constant. When the distance to the moon is closest to the earth, the moon will be big and round, and it looks as if it is very low.

In addition, the atmosphere on the surface of the moon is thin and the heat preservation effect is not good. There is almost no atmosphere on the surface of the moon. During the day, the sun shines directly on the surface of the moon, and the solar radiation does not weaken, and the temperature is high. At night, there is no atmospheric reverse radiation, and the surface of the moon loses a lot of heat and the temperature is low, so the temperature on the moon is not as regulating as the earth's atmosphere.

During the lunar revolution:

Period of revolution has a duration of 27.32 days (the same as rotation), and its direction of motion is counterclockwise around the earth from west to east. The moon, commonly known as the moon, is also called the moon. In ancient China, it was also called Taiyin, Xuantu, Chanjuan and Wangshu. It is the only natural satellite on the earth and the fifth largest satellite in the solar system.

The diameter of the moon is slightly more than a quarter of that of the earth, and its mass is about 1/8 1 of the earth. Compared with the surrounding planets, it is the largest satellite in volume and mass.
