Jun 24, 2013 11:19 IST

The largest as well as the brightest moon of the year 2013, called the Supermoon was observed on 23 June 2013 as it passed the closest point to Earth. Supermoon is said to be that situation when the natural satellite of the Earth is closer to Earth in the orbit than every day. This effect can be noticed when it happens at same time like the full moon.

Therefore the Supermoon seems very big, even though the only difference is in the distance from Earth. This kind of a moon is called Supermoon because of its very noticeable alignment. The distance of moon varies from Earth because it follows the elliptical orbit than the circular one.
 
Concept of Perigee and Apogee

Nasa explained that in 2013, the Supermoon is around 14 percent larger as well as 30 percent brighter than the typical Full Moon. This happens when the moon reaches perigee, which is the closest distance that moon, can reach to Earth during course of its orbit.

Perigee is a situation when the moon is around 356992 km away in comparison to 405696 km away, which is the farthest distance from the Earth (apogee).

Effects of Supermoon on Earth

The effects of Supermoon on Earth are very minor. It does not affect the Earth’s internal energy balance. Scientists explained that this will not cause any natural disasters. The only significant impact of Supermoon is on the tides. Next Supermoon would appear in August 2014.
