Moon's giant crater created by huge protoplanet collision

Everyone knows the moon has a face, but do you actually know what that face is made of?

It's just a cute way to refer to the tremendous collisions that disfigured the giant cheese ball, which was actually once a part of earth.

That is, until it was smashed into something the size of a planet.

One of the bigger visible craters is called the "imbrue basin," and it's what we see as the right eye of the moon.

It's actually incredible that this crater is visible from Earth considering how far away the moon is.

Granted, the crater stretches across 750 miles.

Scientists from NASA and Brown University are saying the basin formed roughly 3.6 billion years ago after an object smashed into it. This object is described as a protoplanet.

According to Dictionary.com, a protoplanet is simply a large body of matter in orbit around the sun, or a star thought to be developing into a planet.

The researchers are saying the object must have been as big as 150 miles across, and they don't even believe the collision was head on. Due to the crater it left, they've concluded it must have hit the moon on a slant.

The studies are also leading scientists to conclude that marks on the moon, and other planets, suggest collisions like this were likely much more common.

Think about this: humans currently do not have a plan for asteroids. If people of this generation were alive back then, even with all of modern science's advances, there definitely wouldn't have been a plan in effect.
