Worm Moon? Why does this supermoon have such an odd name, and when can you see it?

The moon will become full on Monday morning and when it does, it will be a supermooon, NASA says — and one with a pretty bizarre name.

The Worm Moon will be full at 1:48 EDT, according to NASA.

But if waking up in the middle of the night isn’t quite your cup of tea, don’t worry; you’ll still be able to see it. The Worm Moon will stay full through early Wednesday.

The Worm Moon is considered the last full moon of winter and is named after earthworm casts that appear as the ground thaws, NASA reported. It also signifies the time of year when earthworms and grubs come out of dormancy, according to the Farmer’s Almanac.

The Worm Moon was also known by other names among Native American tribes, including the Crow Moon — in honor of cawing crows that signify the end of winter —, the Crust Moon — after crusty snow caused by daily thawing and re-freezing —, the Sap Moon and the Sugar Moon, NASA reported.

This Worm Moon will also be a supermoon. A supermoon occurs when a moon is within 90% of perigee; its closest approach to Earth in a given orbit, according to NASA.

Astrologer Richard Nolle coined the term in 1979, and a typical year may see as many as four supermoons.

This year, the four full moons from February to May will be supermoons, NASA says, with April’s narrowly edging out the Worm Moon as the closest to Earth.
