Where did the Moon come from? Some scientist say it originated elsewhere and Earth gravity positioned the Moon in its orbit. Where was it before this happened? Other theories suggest that the Moon might have been ejected during Earth formation. The most popular theory — the giant impact hypothesis — states that the collision of a planetary-sized object with Earth, 95 million years after the formation of the solar system, could easily have knocked off a volume of matter that consolidated later as the Moon. youtube/watch?v=UIKmSQqp8wY
