What is the Supermoon?
A supermoon is a phenomenon when the full moon coincides with the Moon’s nearest approach to Earth in its elliptical orbit. The closest point is termed as perigee. The moon is considered to be a SuperMoon when it is within 90% of the perigee. It is vital to understand that a Supermoon occurs 3-4 times a year. At perigee, the moon is seen 17% larger and 30% brighter than normal, though the difference might not be visible entirely to the naked eye. The last supermoon, also known as the strawberry moon, was seen on June 14 and was 3,63,000 kilometers away from the Earth.
Other names of the Supermoon are Buck Supermoon or Thunder Moon, the Hay or Mead Moon. The term Supermoon though, is not considered an official astronomical term, it was given by Richard Nolle, an astrologer in 1979.
Eye candy for sky watchers and photographers, the Supermoon is said to have tidal effects on the planet causing very high and very low tides.
