The Moon goes through phases because as it rotates around the Earth, different parts of the Moon are made visible to us from the sun’s light.

There are a total of eight moon phases: new, waxing crescent, first quarter, waxing gibbous, full, waning gibbous, third quarter, and waning crescent. These phases repeat every 29.5 days.
