There are a lot of things that we do know about the moon. Its roughly 1/6 the size of the planet earth. Scientists say that it is 4.6 billion years old and that its approximately 238.000 miles from the planet Earth. It was only recently discovered that their is some water on the moon trapped in ice at the poles. Men from the USA have walked six times on the lunar surface. But you know theres just as much we don't know about it. Where did it come from? Some people speculate it may even be a chunk of the earth that broke off. Many people believe that aliens once had bases on the moon and some believe they still visit it on a regular basis. A lot of people believe there are things still on the moon that our goverment knows about but hides or cover up.
