The May Eta Aquariids

Each May, the Eta Aquariid meteor shower puts on a show in the early morning sky. These meteors get their name because they appear to radiate from the constellation Aquarius, near the star Eta Aquarii. The Eta Aquariids are known for their fast, bright meteors and are especially exciting because they are connected to one of the most famous comets in history—Halley’s Comet. Observations of this shower go back hundreds of years, and it continues to impress skywatchers today.
What is a Meteor Shower?
When you see a shooting star, you’re witnessing a tiny bit of space dust burning up in Earth’s atmosphere. These pieces often come from the tails of comets or from asteroid fragments. As Earth moves along its orbit, it sometimes passes through a trail of debris left behind by a comet. When that happens, we see more shooting stars than usual—a meteor shower!
The meteors appear to come from one part of the sky, called the radiant, which is why this shower is named after a star in Aquarius. Meteor showers last for several days, and the number of meteors changes from night to night. The best night to watch is the peak, when Earth moves through the densest part of the debris.
During the Eta Aquariids, you might see 20 to 40 meteors per hour under dark skies. These meteors travel very fast—about 41 miles (66 km) per second—often leaving glowing trails that can linger for a few seconds.
