Supermoon

The phenomenon seen looming out of the sky on Sunday night was the biggest supermoon of 2014, appearing larger than anything seen in the sky for decades.

The reason for the moon’s appearance, and for the hype surrounding the second supermoon of the year, is because its orbit brought it the closest it has been to the Earth in 20 years.

This was due to two variables: firstly, this moon was known as a perigee moon, which occurs when the moon hits the point of its orbit closest to the Earth, which usually means being around 30,000 miles from the planet. Sunday night’s moon was about 863 miles closer.

Secondly, Sunday night’s moon became full within the same hour of being at the perigee point in its orbit, making it appear bigger and brighter than usual, too.
