A supermoon dominated the evening sky over Chattanooga, Tenn., on Sunday, Dec. 3, 2017.

Sunday's full moon was the first of three consecutive supermoons. The next two will occur on Jan. 1 and Jan. 31, 2018.
A supermoon is a full moon or a new moon that approximately coincides with the closest distance that the moon reaches Earth in its orbit, resulting in a larger-than-usual apparent size of the lunar disk as seen from Earth.
