Etymology[edit]

Blend of super and moon

super- +‎ moon

Coined by astrologer Richard Noelle in 1979

SuperMoon is a word I coined in a 1979 article for Dell Publishing Company's HOROSCOPE magazine, describing a new or full moon which occurs with the Moon at or near (within 90% of) its closest approach to Earth in a given orbit (perigee). In short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth.
— Richard Noelle [1]

Noun[edit]

The "Supermoon" of March 19, 2011 (right), compared to a rather "average" moon of December 20, 2010 (left)

Usage notes[edit]

Some claim this is not a syzygy unless a solar eclipse or lunar eclipse also occurs, but most references disagree.
