Many people believe that the Moon was once part of the Earth and broke away millions of years ago. Other people say that it came from another part of space.

There are high mountains, deep valleys and wide flat spaces on the Moon. Animals and plants can’t live on the Moon because it has no air or water. There are no clouds, no rain and no snow, either.

Sound needs air to travel. There is no air on the Moon. So there can be no sound there. The Moon is a silent place.

The Moon has no light of its own. It looks bright because the Sun’s light shines on it. During the day, the rocks become hotter than boiling (沸腾的) water. This is because the Moon is closer to the Sun than the Earth.

The Moon is about 383 thousand kilometres away from the Earth. It takes a spaceship about three days to reach the Moon. But it would take a car nearly six months to travel this way.
