Phases of the Moon

From Wikipedia, the free encyclopedia

The phases of the moon are the different ways the moon looks during the month. As the Moon moves in space, different parts of it face the Sun. This means that different parts of it are lit up. We only see one side of the moon from Earth because it rotates so that one side is always facing us. The moon phase takes between 29 and 30 days. The phases of the moon appears to be a circular disk, which is illuminated to some degree by direct sunlight.
