At its closest point the moon will be only 221,524 miles from Earth, according to NASA. The last time it was this close was on Jan. 26, 1948. This supermoon also has a few other titles: The "Beaver Moon" and sometimes the "Frosty Moon." Each month's full moon has a variety of nicknames, most given to them by Native Americans. According to the Farmer's Almanac the tribes kept track of the seasons by giving each moon a name. Photo: © James "Bo" Insogna.
