The summer is about to get pretty super for all of you skygazers out there. You can expect three supermoons over the next three months.
Have you ever wondered why some full moons look larger than others? Scientists call it a perigee moon. It happens when a full moon occurs on the side of the moon closest to the earth. These full moons look bigger and brighter than others because the "perigee" side of the moon is 50,000 km closer to the earth than the other side.
Supermoons occur on July 12, August 10 and September 9 this summer.
On August 10th it becomes full during the same hour as perigee—arguably making it an extra-super Moon."
