A supermoon is a full moon that comes closest to the Earth than any other time during its orbit. The moon appears as a giant ball hanging in the night sky. Technically its called a perigee moon and oribits 225,000 miles from earth.
A supermoon is also called a Perigee moon and appears approximately 15 percent bigger and 30 percent brighter than a normal full moon. Its an awesome sight.
Five days ago, on August 10 this year we had a particularly bright supermoon, its orbit came closer than its usual proximal swing-by. Supermoons are regular appearances in our skies, occurring about every 13 months.
When the moon is furthest away from the earth during its orbit, its called an Apogee moon and orbits 250,000 miles from earth.
