The moon made its closest approach to Earth since 1948 Monday, creating a phenomenon called a “supermoon.”

A supermoon is when the moon appears to be exceptionally large since it is approaching the Earth much more closely than usual. When the moon rose Monday morning, it was about 14 percent larger and 30 percent brighter than usual.

This will be the biggest full moon of the decade, and a similar “supermoon” won’t appear again until November 2034. Similar supermoons occured in January, 1912, and January, 1930.

The moon got within 221,524 miles of Earth’s surface at roughly 6:15 a.m. Eastern Standard Time Monday, a distance which is measured from the center of the Earth to the center of the moon, is within 85 miles of the moon’s closest possible approach to Earth, and far closer than its average distance.

The biggest effect of the supermoon is a dramatically larger than range of high and low ocean tides.
