If you have looked into the night sky, you may have noticed the Moon appears to change shape each night.

Some nights, the Moon might look like a narrow crescent. Other nights, the Moon might look like a bright circle. And on other nights, you might not be able to see the Moon at all. The different shapes of the Moon that we see at different times of the month are called the Moon’s phases.
