The Moon

The Moon is the Earth's only natural satellite. As it orbits the Earth each month, it appears to change from a crescent to a full circle and back again, glowing in the sky as it reflects the sun's light. Humans have been fascinated by the Moon for centuries and in 1969 we even visited for the first time. But how did it get there? What is it made from? And why does it go through different phases?
