The moon will be fullest at 2:48 p.m. ET on Sunday afternoon, according to NASA.

This will be the year's first supermoon, meaning the moon is slightly closer to Earth and therefore appears bigger and brighter in the sky. The Worm supermoon is the fourth brightest moon of 2021, according to Earth Sky.

In the Hindu month of Phalguna, this month's moon marks the Holi Festival, according to NASA, which celebrates the beginning of spring.

The Native American tribes in the South call the March full moon the Worm moon because of the earthworm casts, soil that the worms digest, become visible as the ground thaws.

Other Native American tribes have different names for the full moon in March that still relate to animals, according to the Western Washington University Planetarium website.

The Algonquin tribe northeast of the Great Lakes call the March full moon "namossack kesos" or "catching fish." In the northern plains of Canada, the Cree tribe call it "migisupizum" or "Eagle moon."

Typical of a normal year, 2021 will also have 12 full moons. (Last year had 13 full moons, two of which were in October.)

Here are all of the full moons remaining this year and their names, according to The Old Farmer's Almanac:

April 26 -- Pink moon

May 26 -- Flower moon

June 24 -- Strawberry moon

July 23 -- Buck moon

August 22 -- Sturgeon moon

September 20 -- Harvest moon

October 20 -- Hunter's moon

November 19 -- Beaver moon

December 18 -- Cold moon

Be sure to check for the other names of these moons as well, attributed to the different Native American tribes.

Here is what else you can look forward to in 2021.

Meteor showers

There is a bit of a wait until the next meteor shower, the popular Lyrids, in April. The Lyrids will peak on April 22 and will be best seen in the Northern Hemisphere -- but the moon will be 68% full, according to the American Meteor Society. This may make the meteor shower less visible.

The Eta Aquariids follow soon after, peaking on May 5 when the moon is 38% full. This shower is best seen in the southern tropics, but will still produce a medium shower for those north of the equator.

The Delta Aquariids are also best seen from the southern tropics and will peak between July 28 and 29 when the moon is 74% full.

Interestingly, another meteor shower peaks on the same night -- the Alpha Capricornids. Although this is a much weaker shower, it has been known to produce some bright fireballs during the peak. It will be visible for those on either side of the equator.

The Perseid meteor shower, the most popular of the year, will peak between August 11 and 12 in the Northern Hemisphere, when the moon is only 13% full.

Here is the meteor shower schedule for the rest of the year, according to EarthSky's meteor shower outlook.


October 8: Draconids
October 21: Orionids
November 4 to 5: South Taurids
November 11 to 12: North Taurids
November 17: Leonids
December 13 to 14: Geminids
December 22: Ursids


Solar and lunar eclipses

This year, there will be two eclipses of the sun and two eclipses of the moon -- and three of these will be visible for some in North America, according to The Old Farmer's Almanac.

A total eclipse of the moon will occur on May 26, best visible to those in western North America and Hawaii from 4:46 a.m. ET to 9:51 a.m. ET.

An annular eclipse of the sun will happen on June 10, visible in northern and northeastern North America from 4:12 a.m. ET to 9:11 a.m. ET. The sun won't be fully blocked by the moon, so be sure to wear eclipse glasses to safely view this event.

November 19 will see a partial eclipse of the moon, and skywatchers in North America and Hawaii can view it between 1 a.m. ET and 7:06 a.m. ET.

And the year ends with a total eclipse of the sun on December 4. It won't be seen in North America, but those in the Falkland Islands, the southern tip of Africa, Antarctica and southeastern Australia will be able to spot it.

Visible planets

Skywatchers will have multiple opportunities to spot the planets in our sky during certain mornings and evenings throughout 2021, according to the Farmer's Almanac planetary guide.

It's possible to see most of these with the naked eye, with the exception of distant Neptune, but binoculars or a telescope will provide the best view.

Mercury will look like a bright star in the morning sky from June 27 to July 16, and October 18 to November 1. It will shine in the night sky from May 3 to May 24, August 31 to September 21 and November 29 to December 31.

Venus, our closest neighbor in the solar system, will appear in the western sky at dusk on the evenings of May 24 to December 31. It's the second brightest object in our sky after the moon.

Mars makes its reddish appearance in the morning sky between November 24 and December 31 and will be visible in the evening sky between January 1 and August 22.

Jupiter, the largest planet in our solar system, is the third brightest object in our sky. It will be on display in the morning sky between February 17 and August 19. Look for it in the evenings of August 20 to December 31 -- but it will be at its brightest from August 8 to September 2.

Saturn's rings are only visible through a telescope, but the planet itself can still be seen with the naked eye on the mornings of February 10 to August 1 and the evenings of August 2 to December 31. It will be at its brightest between August 1 to 4.

Binoculars or a telescope will help you spot the greenish glow of Uranus on the mornings of May 16 to November 3 and the evenings of January 1 to April 12 and November 4 to December 31 -- but at its brightest between August 28 to December 31.

And our most distant neighbor in the solar system, Neptune will be visible through a telescope on the mornings of March 27 to September 13 and the evenings of September 14 to December 31. It will be at its brightest between July 19 and November 8.
