Super Moon

Super Moon (19-Mar-2011)

A supermoon is 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.

The term supermoon is not widely accepted or used within the astronomy or scientific community, who prefer the term perigee-syzygy.Perigee is the point at which the moon is closest in its orbit to the Earth, and syzygy is full or new moon, when the Earth, the moon and the sun are aligned. Hence, supermoon can be regarded as a combination of the two, although they do not perfectly coincide each time.
