This weekend Saturday the 22nd and Sunday the 23rd will mark the peak of this year's supermoon when the moon makes its closest pass to Earth of 2013. It's known as the perigee full moon, according to EarthSky, and it's the largest of the half-dozen-or-so supermoons that occur annually.

 

Supermoons occur when the sun, Earth and moon align, with the Earth in the middle. As a result, gravity pulls the moon closer, reports CNET.
