Supermoon is a term used by astrologers to denote a nearly full or new moon coinciding with its closest position to Earth (perigee). The term is not widely accepted, especially in the scientific community.
The 19th March 2011 supermoon will be one of the nearest approaches in the past 18 years, with an exact distance of 356,577 kilometres (221,567 mi),[1] though this is only a few km less than average perigee.
