Lyrid Meteor Shower

The Lyrids are coming to a night sky near you. In 2021, they will peak late on the 21st and early on the morning of the 22nd (which is also Earth Day).

The Lyrids are an average meteor shower expected to produce about 10-20 meteors an hour on a dark night. But it’s still worth checking out! In the past the Lyrids have unexpectedly created large bursts of up to 100 meteors per hour.

These meteors come from a stream of dust grains left behind by Comet Thatcher (C/1861 G1). Comet Thatcher has a 415-year orbit around the Sun and was last seen near the Earth in 1861. Despite this long orbit of the comet itself, the debris path is constant and each year the Earth passes through the left-behind bits. As these dust grains hit Earth’s atmosphere at high speed, they heat up and disintegrate in flashes of light that we call meteors.

The Lyrids are named after the constellation Lyra (in the Summer Triangle) as this is the direction from which they appear to originate. While the meteors appear to originate from Lyra, they are best seen 30 degrees away from origin, so be sure to keep careful watch across the whole sky.

To view the Lyrids from the UK, head outside anytime after midnight on the night of the 21-22 April.

Look up and keep an eye on the whole sky!

If it’s cloudy on the 21st, you can always try your luck on a nearby day. The Lyrids are active from 13-29 April.
