Look! Up in the sky! It’s 2017’s only supermoon
The only supermoon of 2017 will appear in a sky near you Sunday night — weather permitting.
Bigger and brighter than a typical full moon, the term “supermoon” was coined in 1979 by astrologer Richard Nolle.
According to NASA, it’s used to describe what astronomers would call a perigean full moon: a full moon occurring near or at the time when the moon is at its closest point in its orbit around Earth.
A supermoon can appear as much as
14% bigger and 30% brighter than when a full moon is at its farthest distance from Earth, NASA said.
The exact moment of the full moon is the morning of Dec. 3 at 10:46 a.m. ET,
(9:46 a.m. CT, 8:46 a.m. MT, and 7:46 a.m. PT), Space.com said.
At that moment, the moon will not be visible over most of North America. However, the moon will still appear plenty big when it rises in the eastern sky Sunday evening.
If you miss this one, don’t fret: The first two full moons of 2018 will be supermoons.
