It's called a Harvest Moon because it traditionally provided farmers with more time to pick their crops. Here's what else to know about the full moon.

The skies will light up Tuesday night with a double lunar phenomenon: the Harvest supermoon and a partial lunar eclipse. Supermoons are full moons that appear larger because they happen in tandem with the lunar orbit’s closest approach to earth.

The full harvest supermoon will shine brightly in the night sky Tuesday evening. A partial lunar eclipse, with a “bite” taken from the moon, will also be visible.
