WebbThe most widely accepted origin explanation posits that the Moon formed 4.51 billion years ago, not long after Earth, out of the debris from a giant impact between the planet and a hypothesized Mars -sized body called Theia. It then receded to a wider orbit because of tidal interaction with the Earth.
