The term supermoon refers to a full moon that occurs when our satellite is at perigee, the point at which its orbit brings it closest to our planet. (The moon's orbit is elliptical, and its distance from Earth varies between about 407,000 km at apogee, the point of maximum distance, and about 380,000 at perigee.)
