I always though it was fascinating to learn about and imagine our Earth, long before we came along and ruined it. I was watching a show on the Science Channel recently, and it seems like most scientists now agree that our Moon was formed by a violent collision of an early Earth with another planet sized body. The Moon also used to fill the night sky, as it was much closer to us than it is now. In an new theory, NASA scientists believe that the impact that created our moon would have actually created three moons. The two additional moons would have been only a fraction of the size of our Moon today. Due to their small size, scientists theorize that they would have impacted with the Earth, the Moon, or have just drifted off into space. Perhaps it's because they were made of cheese.
