Only 225, 745 mile from the Earth is the moon. The length of its day is 27.3 days to us. When astronauts travel to the moon takes them 60-70 hours to reach it. Only 59% of the moon is visible to us from Earth, and it is egg shaped not round like it appears. The craters on the moon were formed by meteor crashes thousands of years ago. Some people also claim to have seen things in the moon such as the man in the moon or a bunny.
