The summer of supermoons arrives - PHOTO

If you looked up at the sky you would have seen a perigree moon, more commonly known as a supermoon.It happens when the moon is 30,000 miles closer to Earth than the farthest point in its orbit and the moon looks bigger and brighter.In fact, it is just an optical illusion caused by its position in the sky.It is not that uncommon. Last year we had three although only one made the news. This year we will also have three supermoons with the next occurring on August 10 and then on September 9.(dailymail.co.uk)Bakudaily.az
