supermoon

Perigee full phase

A supermoon is a full moon that appears unusually large and bright because it occurs when the moon is at or near its closest point to Earth in its elliptical orbit.

The term is more popular than scientific—astronomers prefer "perigee-syzygy"—but supermoons generate widespread attention and photography: Did you see last night's supermoon?
