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
