The Moon

Over the course of a month, we can watch the phases of the Moon change from full to new and back to full again. Each night, the Moon looks a little different.

Moon phases describe the amount of the Moon that we can see which is illuminated by the Sun. The phase of the Moon depends on its position relative to the Earth and Sun. As the Moon orbits the Earth, the amount of sunlight falling on the side of the Moon facing Earth changes. The Moon cycles through its phases every 29.5 days. This recurring cycle of phases is the basis for our month.
