The formation of the Moon billions of years in the past is cloaked in thriller. Most astronomers consider the younger Earth, nonetheless cooling off from its formation, was struck by a mars-sized physique referred to as Theia, roughly 4.5 billion years in the past.

Because the proto-Moon orbited Earth, it cooled, and gathered particles from the encompassing area of house. On the time, the Moon was a lot nearer to Earth than it’s as we speak. Over billions of years, gravitational forces between the Earth and the Moon resulted in our planetary companion shifting additional away from our dwelling world.

Researchers at Durham College developed supercomputer simulations, displaying how this historic collision might have unfolded.
