The Eta Aquarid meteor shower 2025 is active between April 19 and May 28 and this year peaks overnight May 5-6. The best time to view the shower will be before dawn on May 6, when the shower’s radiant it at its highest in the sky.
This year, the Eta Aquarids peak at the same time as a bright waning gibbous moon, resulting in significant moonlight interference, which can wash out fainter meteors.
The maximum rate for shooting stars in a clear sky will be about 50 per hour, according to the American Meteor Society (AMS). These fast meteors travel across the sky at about 41 miles (66 kilometers) per second.
Where can you see the Eta Aquarid meteor shower?
Meteor showers are named after the constellation from which the meteors appear to originate. From Earth’s perspective, the Eta Aquarids appear to come from approximately the constellation Aquarius.
Aquarius constellation position:
Right ascension: 23 hours
Declination: -15 degrees
Latitudes: Between 65 and -90 degrees
You can see the Eta Aquarids best in the Southern Hemisphere, where they are one of the most prolific showers of the year. They can also be viewed north of the equator, where observers can expect to see around 10 to 30 meteors per hour during the shower’s peak. All you need to catch the show is darkness, somewhere comfortable to watch and a bit of patience.
Though the Eta Aquarids’ radiant is the Aquarius constellation, it is not the source of the meteors. Don’t look directly at Aquarius to see the meteors, as they will be visible across the night sky. Make sure to move your gaze around to nearby constellations as meteors closer to the radiant have shorter trains and are more difficult to spot. If you only look at Aquarius, you might miss the more spectacular Eta Aquarids.
How can you see the Eta Aquarid meteor shower?
For the best view of the Eta Aquarid meteor shower, go to the darkest possible location, lean back and relax. You don’t need any special pieces of equipment like telescopes or binoculars, as the secret is to take in as much sky as possible and allow at least 30 minutes for your eyes to adjust to the dark. Avoid using your phone and make sure you have a red light setting on flashlights to preserve your night vision.

Best time to view the Eta Aquarids
To see the Eta Aquarids, Bill Cooke, the lead for the Meteoroid Environment Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recommends getting outside at 2:00 a.m. local time. From then on, the rates will continue to increase until dawn.
“The Etas are not a shower that you can go out to see after sunset because the radiant won’t be up,” Cooke wrote.

What causes the Eta Aquarid meteor shower?
Similar to October’s Orionid meteor shower, the Eta Aquarid meteor shower is caused by ice and dust left behind by a celestial icon: Halley’s Comet.
When Earth passes through the comet’s debris, the “comet crumbs” heat up as they enter Earth’s atmosphere, producing impressive “shooting stars” that streak across the sky.
Halley’s Comet takes about 76 years to orbit the sun once and will not enter the solar system again until 2061.
The comet is named after English astronomer Edmond Halley, who examined reports of comets approaching Earth in 1531, 1607 and 1682. He concluded that these sightings were all of the same comet returning over and over again. Halley predicted the comet would return in 1758. Though he did not live to see the comet’s correctly predicted return, it was later named in his honor.
