What is the Eta Aquariid meteor shower?

The Eta Aquariids is a moderately active meteor shower associated with the Comet Halley.

When is the Eta Aquariid meteor shower in 2021?

The Eta Aquariid meteor shower will peak between midnight and dawn on 6 May 2021.

This shower favours the Southern Hemisphere and will appear low in the sky for Northerly latitudes (such as the UK) in the early predawn hours.

Nevertheless, it should still be possible to see the shower in the eastern sky, even when the radiant is below the horizon.

Meteors are pieces of debris which enter our planet’s atmosphere at speeds of up to 70 kilometres per second, vaporising and causing the streaks of light we call meteors.


Where does the name Eta Aquariid come from?

Like with most meteor showers, the name comes from the constellation in the night sky that it appears to radiate from. In this case, it’s the Aquarius constellation. But why isn’t it called the 'Aquarid' meteor shower? This is because, more specifically, the name comes from one of the stars from this constellation: Eta Aquarii.

How can I see the Eta Aquariid meteor shower?

Hunting for meteors, like the rest of astronomy, is a waiting game, so it's best to bring a comfy chair to sit on and to wrap up warm as you could be outside for a while. They can be seen with the naked eye so there's no need for binoculars or a telescope, though you will need to allow your eyes to adjust to the dark.
