The Moon is the only natural satellite of the Earth and the fifth largest satellite in the Solar System.
A full moon will make its closest approach to Earth this year, on June 22 into June 23, and it won’t be your regular once a month full moon because it will look more impressive than any full moons seen so far in 2013.
This most recent occurrence of a Supermoon when the moon is the closest and largest full moon of the year and the Moon’s closest encounter with Earth for all of 2013. It will not be so close again until August 10, 2014.
There were Supermoons in 1955, 1974, 1992, 2005 and March 2011.
A Supermoon is a full or new moon at its closest approach (called lunar perigee) the Moon makes to the Earth on its elliptical orbit, this will make the size of the lunar disk as seen from Earth, look somewhat larger.
The term “Supermoon”, technically called a Perigee Full Moon by astrologer Richard Nolle in 1979, and is the term used to describe when the moon is full or new and is at 90% or greater mean perigee distance to Earth.
