The Eta Aquariid meteor shower is an annual event that occurs as Earth passes through the debris field left by Halley's Comet (1P/Halley). This comet, named after Edmond Halley, has a roughly 76-year orbit, and last visited the inner solar system in 1986. It won't be visible again until 2061.
The radiant, or point of origin, of the Eta Aquariids is near Eta Aquarii, a star in the Aquarius constellation. However, the meteors can appear anywhere in the sky. Observers in the southern hemisphere typically have a better view because the radiant rises higher above the horizon.
**Viewing Tips:** - Find a dark location away from city lights. - Allow your eyes to adjust to the darkness for about 20 minutes. - Face east in the hours before dawn. - Be aware that moonlight can reduce the visibility of fainter meteors.
While rates can reach up to 50 meteors per hour under ideal conditions, the waning gibbous moon in 2026 may make spotting them more challenging. Consider positioning yourself so the moon is out of your direct line of sight.
The Eta Aquariid meteor shower is caused by Earth passing through the debris field of Halley's Comet.
The peak viewing times are in the pre-dawn hours of May 5th and 6th.
A dark location away from city lights is ideal. Southern hemisphere observers generally have better views.
The meteors travel at approximately 40 miles per second.
