A controversial new theory has been proposed suggesting that our moon didn't form around the Earth but instead formed in orbit around Mercury and later migrated out until it was caught by Earth's gravity and roped in to orbit.
The moon may have been adopted by our planet instead of descended from it. If a new twist on a decades-old theory is right, conditions in the early solar system suggest the moon formed inside Mercury's orbit and migrated out until it was roped into orbit around Earth.
