Supermoon

Astrophysical Concepts

A supermoon is a full moon or new moon that nearly coincides with perigee, the Moon's closest point to Earth in its orbit. It appears slightly larger than usual when viewed from Earth. The technical term is perigee syzygy, although supermoon has no precise astronomical definition because of its astrological origin. Claims linking supermoons to earthquakes or volcanic eruptions have not been supported.

Technical name: Perigee syzygy
Apparent effect: Slightly larger-than-usual lunar disk
Opposite phenomenon: Micromoon
