2021 Astronomical Calendar: Full Moons, Meteor Showers, and Eclipses to Watch for This Year

From the great conjunction to impressive comets, 2020 was filled with exciting astronomical events, but there’s even more on the horizon (and in the night sky) for 2021. This year, stargazers can look forward to meteor showers, lunar eclipses, supermoons, and even a total solar eclipse. To help you keep track of them all, we’ve created this astronomical calendar with some of 2021’s celestial highlights, thanks to information gathered from NASA, the American Meteor Society, and The Old Farmer’s Almanac. 

Before planning your year of stargazing, there are a few basic things to know about each of these events. You’ve probably seen numerous full moons during your lifetime, but do you know what a supermoon is? Supermoons happen when the full moon occurs at perigee — the point at which the moon appears closest to the Earth in its orbit. Full moons and supermoons are easy to spot wherever you are, but you might want to head somewhere with less light pollution for the best chance of seeing shooting stars during a meteor shower.

Lunar eclipses and solar eclipses are only visible in certain parts of the world — and this year’s total solar eclipse can only be seen in Antarctica.

Want to take your stargazing to the next level? Invest in a telescope or good binoculars, so you can see even more in the night sky. 

Below, find the dates of every full moon (including two supermoons), two solar eclipses, two lunar eclipses, and five major meteor showers in 2021. (Note that the below dates are according to UT, and that we’ve listed the predicted maximum of the meteor showers. For some of these showers, you might be able to spot a few shooting stars before and after that date.)
