It will be hard to miss...

The first and only visible Supermoon of 2017 is this weekend. Overnight Sunday into Monday December 4 the Full Cold Moon will appear 16% brighter and 7% bigger in the night sky.

Because the moon's orbit isn't perfectly circular, its distance from Earth varies. A Supermoon occurs when the moon is at its closest point to Earth.

According to, Skywatchers will see the Supermoon at its closest approach to Earth at 4AM Monday. At its peak the moon will look HUGE.

The moon is usually 252,000 miles from Earth. During a Supermoon it's about 222,000 miles from Earth.
