You may have 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.
A supermoon just means the moon looks a bit bigger than usual since its a bit closer to the Earth than usual. "Because the orbit of the moon is not a perfect circle, the moon is sometimes closer to the Earth than at other times during its orbit," NASA scientist Noah Petro says. "There’s no physical difference in the moon. It just appears slightly bigger in the sky. It’s not dramatic, but it does look larger." And for the next supermoon, try to stay out of the ocean.
