[Jitendra Hy-do-u-no-us?]

It's a term — or, more specifically, a branding — of relatively recent origin; it came not from astronomy, but astrology, and was coined by astrologer Richard Nolle in 1979. Nolle arbitrarily defined a supermoon as a new or full moon that occurs when the natural satellite is at or near (within 90 percent of) its closest approach to Earth in a given orbit (perigee).
