k Formation of the Moon, artwork Formation of the Moon. Artwork of a Marssized protoplanet Theia looming over a protoEarth with which it is about to collide. This illustrates the giant impact theory of the formation of the Moon. This theory says that an object about the size of Mars collided with the Earth around 4.6 billion years ago, soon after they both formed. The impact was sideon, rather than a direct impact. Material from the outer layers of both bodies was thrown into orbit around the Earth, forming a ring. This then coalesced to form the Moon.

Formation of the Moon, artwork

Formation of the Moon. Artwork of a Mars-sized protoplanet (Theia) looming over a proto-Earth with which it is about to collide. This illustrates the giant impact theory of the formation of the Moon. This theory says that an object about the size of Mars collided with the Earth around 4.6 billion years ago, soon after they both formed. The impact was side-on, rather than a direct impact. Material from the outer layers of both bodies was thrown into orbit around the Earth, forming a ring. This then coalesced to form the Moon. For the Moon being formed following this collision, see image C016/5353.
