A supermoon occurs when the Moon is at perigee to Earth. You may be scratching your head, trying to figure out what the astronomical term means. I’m gonna save you a trip to Google and explain. Simply put: The Moon is closer to Earth than usual, making it appear larger than normal. So, if you’re looking at the night sky and thinking about why the Full Moon is bigger and brighter, it just means it is in a closer orbit to our planet. However, note that the emotional effects of the lunation might hit hard. This season has three supermoons: October 6, November 5, and December 4.
