Look up! August's 'blue supermoon' won't be seen again until 2037

WATCH: What is the blue moon and is it actually blue?

A rare blue supermoon, a type of full moon, is set to appear at the end of August.

The moon will be especially big and bright and rise above the Earth's horizon at around 222,000 miles away on the night of Aug. 30, according to NASA. The moon will be a supermoon, or a moon that appears to reach its perigee, the point where it is closest to the center of Earth.

The next blue supermoon is expected to occur January 2037, which is what makes this one rare.
