Did you see it? Sunday night's full moon appeared bigger and brighter than normal, thanks to amazing timing.
The supermoon, as it's commonly called, happens when a full moon coincides with the moon's closest approach to the Earth during its elliptical orbit around us. The result is spectacular.
During a supermoon, the full moon appears 14% bigger and 30% brighter than when it is at its farthest, says Ben Burress, an astronomer with the Chabot Space and Science Center in Oakland.
The moon was 190,000 miles from the Earth, 20% closer than its farthest point, when it is 240,000 miles away.
