Brief introduction to nouns:
The moon is the fifth largest satellite in the solar system, with an average radius of about 1737. 10 km, equivalent to 0.273 times that of radius of the earth. The mass is close to 7.342× 10? Kilogram, equivalent to 0.0 1.23 times of the earth. The surface of the moon is covered with craters, which may be formed by the impact of small celestial bodies. The average distance between the moon and the earth is about 384,400 kilometers, which is about 30 times the diameter of the earth.
On the front of the moon, there are a large number of huge impact craters, which are filled with basalt lava flows from dark volcanoes, forming a vast plain called the Moon Sea. In fact, there is not a drop of water in the moon sea. There are bright, ancient plagioclase highlands and striking impact craters between the moon and the sea.
Orbital motion:
The moon moves around the earth in a circular orbit. The great circle cut by this orbital plane on the celestial sphere is called "White Road". The ecliptic plane is neither coincident with the celestial equator nor parallel to the ecliptic plane, and its spatial position is constantly changing. The cycle is 27.32 days. The average inclination of the lunar orbit (the white road) to the ecliptic of the Earth orbit is 5 09'. But it is known that the moon gradually leaves the earth at an average speed of 3.8cm per year.
Libra movement:
Because the rotation period of the moon is exactly the same as that of its period of revolution, it can only be seen from the earth that the moon always faces the earth with the same face. From the early days of the formation of the moon, the earth was affected by a moment, which led to the slow rotation speed. This process is called tidal locking.
