3. The Formation of the Moon

About 60 million years after the Solar System originated, the Moon was formed. Roughly 4.51 billion years ago, material from Earth was launched into space due to an impact from a large celestial body named Theia. This material was then pulled around by gravity and formed into the Moon.

The Moon is thought to have formed from the fusion of two different celestial bodies. The reasoning for this is that the far side of the Moon has a crust that is 31 miles thicker than the crust on the near side. Experts believe that the impact that created the Moon would have formed a lunar magma ocean on its surface.
