Quizplus · Accepted Answer

The most widely accepted theory for the formation of the Moon is the impact theory, which suggests that an object about the size of Mars collided with Earth early in its history, ejecting material that later formed the Moon. This theory is supported by evidence from the Apollo missions, including the similarity in composition between Moon rocks and Earth's mantle and the fact that the Moon has no iron core, which is consistent with an impactor stripping away the Moon's mantle and leaving only a small metallic core.
