The Moon is a lot smaller and closer to Earth than the Sun.
The Moon orbitAn orbit is a regular, repeating path that one object in space takes around another one. the Earth. This takes 28 days or one lunar month.
The Moon reflects light from the Sun and that is why we can see it. It is not a source of light but acts like a mirror.
As it orbits the Earth, we see the Moon from different angles each night. It appears to change shape as we see different parts of the surface lit up. These shapes are called the phases of the Moon.
