Question

Where does the moon come from?

Answer 1

The origin of the Moon is usually thought to be that a Mars-sized body struck the Earth, making 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 alternate explanations, and research into how the Moon came to be continues Other proposed scenarios include captured body, fission, formed together (condensation theory), planetisimal collisions (formed from asteroid-like bodies), and collision theories
