What is a supermoon or super moon?

Category: Science


Supermoon, Super MoonA super moon (supermoon) or perigee is essentially a full moon that occurs in conjunction with a close position, during its elliptical orbit, to the earth. During this phenomenon, the moon will get as close as 356,577 km (221,566 miles) away and appear to be about 14% larger than usual. A perigee isn’t necessarily rare since it occurs 4 to 6 times per year. It becomes unusual, however, when a full moon occurs at the same time. The last time this took place was around 18 years ago on January 19th, 1992. According to astronomers, there is no significance between a supermoon and any natural disasters that may transpire (Japan Tsunami) even though they appear to be linked.
