What star, satellite or planet does the moon belong to?

The moon that people see is what we call the moon, which is naturally formed in the universe. It can balance the rotation of the earth. Many people doubt whether the moon is a satellite or a planet. Then let's use constellation knowledge to reveal which star the moon belongs to. Is it a satellite or a planet?

Which star does the moon belong to? Answer: satellite

What is a satellite? It refers to a natural celestial body that runs around the planet and periodically in a closed orbit. Satellites can also be called satellites. Man-made satellites are devices built by human beings, which are launched into space by spacecraft such as rockets and space shuttles, and orbit around the earth or other planets like natural satellites. Usually gas planets have many moons. The eight planets * * * have 59 satellites. Except Mercury and Venus, all the other planets are surrounded by satellites. According to the number of satellites, the ranking order is Saturn/KOOC-0/8, Uranus/KOOC-0/7, Jupiter/KOOC-0/6, Neptune 8, Mars 2 and Earth/KOOC-0/. The size and quality of different satellites vary greatly. There are seven satellites with a radius greater than 1000km, and the moon is one of them.

What is a planet? Usually refers to a celestial body that does not emit light by itself and surrounds a star. Its revolution direction is often the same as the rotation direction of the surrounding stars. Generally speaking, the planet needs to have a certain mass, and the mass of the planet should be large enough to approximate a sphere, so that nuclear fusion reaction can occur like a star.

What is a satellite system? Satellite galaxies is a galaxy surrounded by the gravity of another big galaxy. In a pair of intertwined galaxies, if one of them is larger than the other, then the larger one is the "main" galaxy and the smaller one is the satellite galaxies. If two galaxies are almost the same size, they will be called binary systems.

The formation of satellite system The source of angular momentum of satellite system is the same as that of planetary rotation. However, when considering the formation of satellites, it must be analyzed as the formation process of planetary systems. First of all, in the process of contraction, the original star embryo of the planetary system will form a rotating sphere for the same reason as when the planetary system was formed. This sphere will gradually become a flat nebula disk in the process of shrinking to its center of gravity, forming a planet in the central part of the nebula disk and a satellite in the peripheral part of the nebula disk. Consider two situations.

Satellite System: Introduction of earth-moon system The Earth and its natural satellite, the Moon, form a celestial system called earth-moon system. In the Earth-Moon system, the earth is the central celestial body, so the movement of earth-moon system is generally described as the movement of the moon around the earth. However, the revolution of the moon around the earth is actually the revolution of the earth and the moon relative to their concentric centers. Because of this revolution, * * * homocenter has a displacement in the interior of the earth with the period of the earth's sidereal moon.

Most scientists believe that the formation of the earth-moon system is the result of the moon hitting the earth. When the collision between the moon and the earth reaches the maximum, the energy between them is also transformed into the maximum. At this time, the plate, soil, stone sand and seawater return to the earth, and the centrifugal force generated by the earth's rotation makes the moon leave the earth. When the moon left, the earth-moon system was born.
