The Full Beaver Supermoon gets its name because it tends to happen around the same time as when beavers start to take shelter in their lodges, according to the Old Farmer’s Almanac. It’s also historically when hunters would trap beavers for their pelts.

This November's full moon is a supermoon, meaning it's closer to Earth in its orbit and appears larger and brighter than usual, according to NASA. The beaver moon will be the fourth and final supermoon in this series.
