Today’s Video of the Day from the European Space Agency describes various theories regarding the origin of the Moon.
While it is known that the Moon formed over 4.5 billion years ago, exactly how this happened remains a mystery.
There are four major theories about the origin of the Earth-Moon system, and the most popular is the Big Splash theory.
This is the idea that a large object collided with Earth, destroyed its mantle, and sent material flying into orbit that formed the Moon.
