On Saturday night, July 12, you may have noticed that the moon looked unusually large.
That's because it was the "supermoon," which happens when two phenomenon occur at the same time: the full moon and the "perigee moon." The perigee moon is when moon passes closest to earth causing it to look about 14% larger and 30% brighter than usual. It looks even larger when it hangs low over the horizon, as it does when it is rising, for reasons scientists can't completely explain.
Don't worry if you missed it though. You can catch another supermoon on August 10 and September 9.
