Supermoons tend to look larger and brighter in the sky, offering a rare treat for sky gazers.
The variability is caused by the fact that the moon's orbit around the Earth is egg-shaped and slightly irregular, making for times when it is closer or farther away from us. At its closest point this cycle, at 6:21 a.m. ET (11:23 UT) on November 14, the moon will be just 221,524 miles from Earth, as measured from the center of both bodies.
The full moon won’t get this close to us again until November 25, 2034. And the closest full moon to Earth this century will occur on December 6, 2052, when our celestial neighbor will be just 221,472 miles away.
