The formation of the Moon?

Recommended Posts

There is a theory regarding it. Scientists believe that many millions of years ago a large celestial body, probably a massive asteroid named Theia collided with the earth causing a huge spread of materials and rock chunks. Those materials accumulated under gravitational influence to form the moon. This theory has a major evidence to support. The nearer side of the moon, that is, the side which faces the earth, has thinner crust than the other side. According to the theory, the heat of magma from earth after the impact caused the facing side of the moon to melt, thereby delaying the process of cooling and solidification. This has resulted in a more thick crust to form on the far and cool side than on the near side.

Here's a link to a prior SFN discussion where we talked about a relatively recent article on this very subject. That discussion's OP contains a link to an article that discusses a theory regarding a collision between Earth and a sister planet, Theia. I don't think anybody knows for sure, but there's a couple of good theories and a lot of research on the subject.

​I thought the other side of the moon has never been seen.
