Origin of the Moon - Wikipedia
The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.

2023年11月22日 · The Moon completes an orbit of the Earth every 27.3 days (approximately 655 hours). The Moon also rotates on its axis. Because of tidal forces, it completes one revolution every 655 hours. So, one “side” of the Moon is always facing the Earth, and the other “side” is always facing away from the Earth.
Moon - Wikipedia
The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth. The Moon's gravitational pull is …
