Extreme Supermoon


SUPERMOON
Credits : JPL/NASA
The term supermoon was coined by astrologer Richard Nolle in 1979, defined as
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 . In short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth.

The technical term for this phenomenon is a perigee - syzygy wich is shortened to "supermoon"!!
            Well March 19 2011 has witnessed one of the "ExtremeSuperMoon" phenomenon..... which is repeating itself after an interval of 18 yrs..
