March's full moon also happens on the same day as the spring equinox, welcoming in the season. The last time these two things happened on the same day was March 1981.
No matter what timezone you're in, look out for the supermoon at 9:43 pm ET on Wednesday.
March's full moon is also known as the Full Worm Moon. Traditional and Native American names for each full moon of the year are derived from how they helped track the seasons. In this case, the ground began to soften in March so that the earthworms could appear, drawing more birds to feed, according to Farmer's Almanac. This moon is associated with spring for that reason.
But the asteroid is expected to pass by safely and without incident on March 21 and 22, depending on where you live
