Revolution: Revolves around the earth every 27.3 days
The moon rotates and revolves at the same rate.

3. Phases of the Moon The moon shines by reflecting light from the sun.
The moon is like a mirror. It reflects the light from the sun onto earth at night

When that light is not able to reach the moon, it becomes dark which we call the phases.
There are 8 phases.
Each phase depends on how much light you can see.
