Eta Aquarid Meteor Shower

Eta Aquarid Meteor Shower

Get the hot chocolate and blankets ready – the Eta Aquarids are coming to a night sky near you. In 2021, peak activity occurs midnight and dawn of 6 May.

Twice a year, the Earth crosses the orbital path of Halley’s Comet – once in May and once in October. Comets constantly shed dust and stones as they fly around the Sun, and it is this debris along Halley’s path that causes the Eta Aquarids. The debris hits Earth’s atmosphere at nearly 150,000 kilometres an hour and burns up in bright, short blazes about 80 kilometres off the ground. In October this same debris trail causes the Orionid meteor shower.

Halley’s Comet takes 76 years to orbit the Sun and will next be visible from Earth in 2061.

How to Watch

The Eta Aquarids are named after the southern constellation Aquarius as this is the direction from which they appear to originate. 

While the meteors appear to originate from Aquarius, they are best seen 30 degrees away from origin, so be sure to keep careful watch across the whole sky.

To view the Eta Aquarids from the UK, head outside anytime after midnight on the night of the 6 May.

Look up and keep an eye on the whole sky.

If it’s cloudy, you can always try your luck on a nearby day. The Eta Aquarids are active from 18 April – 27 May.
