Supermoons are not particularly unusual—the next full Moon is the biggest of either two, three or four consecutive supermoons, depending on who you ask. The term “supermoon” was first used in 1979 by Richard Nolle, a peddler of astrology, to describe a Moon that is full—when it is directly opposite the Sun, as seen from Earth, and its near side is thus fully illuminated—at the same time that it reaches the closest point to Earth in its orbit.
