Introduction
People have been interested in the Moon since ancient times. One of the reasons for this is that it is the most visible body in the sky, apart from the Sun. Also the Moon is 384,400 km away from Earth, which means it is closer to Earth than the planets. The Moon is known as Earth's satellite because it orbits the Earth. Its location and size makes it very important to planet Earth.
Orbit and spin
The Moon has two types of movements called orbit and spin. The orbit is the path that the Moon travels around the Earth while it spins or rotates on its axis.
