3 straight dazzling supermoons to illuminate the night sky
Cross your fingers for some clear nights over the rest of the year, as three straight supermoons will light up the night sky. Don't miss the first one on Oct. 6.
A supermoon is a full moon that appears larger and brighter than normal because it is at a point known as perigee. Because the moon's orbit around the Earth is elliptical, the perigee is the moon's closest approach to our planet.
"Supermoon" isn’t an official astronomical term, but typically it’s used to describe a full Moon that comes within at least 90 percent of perigee," NASA wrote on its website. "Supermoons only happen three to four times a year, and always appear consecutively."
