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.

The exact moment of the full moon is the morning of Dec. 3 at 10:46 a.m.  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.  Here's more from USA Today.
