Why is the moon a satellite and not a planet? Why is the moon gradually moving away from the earth?

The moon is a planet, commonly known as the moon. In ancient times, it was also called Taiyin and Xuantu. It is the only natural satellite of the earth. A satellite refers to a natural celestial body that orbits a planet and moves periodically in a closed orbit. Why is the moon gradually moving away from the earth? Do you understand? If you need a more detailed introduction, please open the following interpretation!

Why is the Moon a satellite and not a planet?

The reason why the moon is a satellite and not a planet is that the moon revolves around the earth, and the earth is one of the nine planets, so the moon is a satellite of the earth, not a planet. Planets revolve around the sun or other stars, while satellites refer to natural celestial bodies that orbit a planet and move periodically in a closed orbit.

In addition, a planet is a larger celestial body that orbits the sun or other stars and has a mass no greater than that of Jupiter, while a satellite is a natural celestial body that orbits a planet and moves periodically in a closed orbit. Because the moon orbits the earth, and the earth is one of the nine planets, the moon is a satellite of the earth.

Why is the moon moving away from the earth?

If the earth and the moon were just a particle as described in the high school physics exercise book, then the earth's gravity would never push the moon away. But in the real world, they are not only huge balls, but also huge balls that can deform. If you have ever walked on the beach on a moonlit night, you will have a deep feeling of this deformation. The sea surface at the same location will experience two high tides every day - the moon attracts the seawater wrapped around the surface of the earth, forming an ellipsoidal "water ball" with the long axis of the water ball pointing from the earth to the moon. The sea surface in the long axis direction reaches the highest point in a day, which is the "tide"; the sea surface in the short axis direction reaches the lowest point in a day, which is the "tide". Tides and tides are generated because different places on the earth's surface are subject to different degrees of lunar gravity, so in physics, "tidal force" is used to refer to the force generated by the difference in gravity. The earth produces tides under the influence of the moon. Although there is no ocean on the surface of the moon, it will still produce very small stretching deformation under the influence of the earth. It may be considered as a solid "tide".

Is the moon a planet?

The moon is a planet, commonly known as the moon. In ancient times, it was also called Taiyin and Xuantu. It is the only natural satellite of the earth and the fifth largest satellite in the solar system. The diameter of the moon is one-fourth of the earth's, and its mass is one-eightieth of the earth's.

A satellite is a natural celestial body that orbits a planet and moves periodically in a closed orbit. Artificial satellites are also generally called satellites. Artificial satellites are built by humans and launched into space by space flight vehicles such as rockets and space shuttles. They orbit the earth or other planets like natural satellites.
