A super moon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth. The technical name is the perigee-syzygy of the Earth–Moon–Sun system. The term super moon is not astronomical, but originated in modern astrology.The association of the Moon with both oceanic and crustal tides has led to claims that the super moon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions, but this effect is very slight.
The opposite phenomenon, an apogee-syzygy, has been called a micro moon, though this term is not as widespread as super moon.
The most recent super moon occurred on November 14, 2016, the closest to Earth since January 26, 1948, and the next one like this will not be until November 25, 2034.The closest super moon of the century will occur on December 6, 2052.
Occasionally, a super moon coincides with a total lunar eclipse. The most recent occurrence of this was in September 2015, while the next time will be in October 2033.
