Supermoon

You've probably heard the hype about the supermoon. A supermoon occurs relatively often, about once every 14 full moons, when the moon is closest to the Earth. Though many claim that the moon is not really all that much bigger or brighter than usual when it's at perigee (its closest point), it's still a sight to behold. Mark your calendars for Aug. 10, 2014, for the next supermoon ... but try to stay out of the ocean.
