Not one, and not two, but we've got a summer full of three "supermoons" ahead of us -- and the first one is set to peak this Saturday at 7:25 a.m. EDT.
These supermoons -- July 12, Aug. 10 and Sept. 9 -- will appear even bigger and brighter than the average full moon.
What makes these moons so spectacular? A supermoon, also known as a "perigee moon," occurs when a moon turns full around the same time it reaches "perigee," the closest point to Earth along its elliptical orbit.
While this may sound like a rare event, Geoff Chester of the U.S. Naval Observatory told NASA Science News that it’s actually relatively common. Just check out the video above.
“Generally speaking, full moons occur near perigee every 13 months and 18 days, so it’s not all that unusual,” he said. “In fact, just last year there were three perigee Moons in a row, but only one was widely reported.”
On Saturday, the moon will be 222,611 miles away from Earth -- that's 30,000 miles closer than at its farthest distance in 2014. The moon will be at its closest this year on Aug. 10, when it will be 221,748 miles from Earth.
"I guarantee that some folks will think it's the biggest moon they've ever seen if they catch it rising over a distant horizon, because the media will have told them to pay attention to this particular one," Chester told NASA Science News.
