Phases of the Moon

The Moon, Earth's only natural satellite and one of the brightest objects in its sky, appears in the sky in many different shapes. Over the course of a month, the observed shapes result from the interaction of the Moon's orbit around Earth and reflected sunlight. In this interactive resource adapted from the National Air and Space Museum, learn about the relationship between the Moon's orbit and its phases.

This media asset was adapted from Phases of the Moon by the National Air and Space Museum, Smithsonian Institution.
