Yearly Meteor Showers

To help you plan your own meteor adventures, here’s a summary of the best annual showers. Meteor showers are rather unpredictable, and the hourly rates quoted are average Zenithal Hourly Rates (ZHRs) — the number of meteors visible on a perfectly dark night when the radiant is near the zenith.

January 3-4 Quadrantids

This shower radiates from a region near the Draco-Boötes border formerly known as the Quadrant. Peak activity of this shower is limited to no more than one evening. Expect rates of 10-60 Quadrantids per hour, with occasional hourly outbursts of 100 or more.

April 21-22 Lyrids

This is usually a minor shower (average hourly rate between 10-15 meteors)

May 4-5 Eta Aquarids

This shower results from the remnants of the most famous of all comets – Halley’s Comet. Look for about 20 Eta Aquarids radiating hourly from a region near the water jar of Aquarius.

July 28-29 Delta Aquarids

This may be the most prolific meteor swarm of all that produce showers. Unfortunately, the display spreads over many evenings, resulting in a rather modest peak hourly rate of 20-25 meteors.

August 12-13 Perseids

The Perseid shower is perhaps the best-observed because of its richness (hourly rate between 50-100 meteors) and the mild time of year. It's a great first shower for beginners!

October 21-22 Orionids

This is another shower spawned by Halley’s Comet. Look for 20-25 meteors per hour radiating from an area near Orion’s club.

November 3-13 Taurids

This shower, though low in numbers (with an average rate between 10 and 15 per hour), produces some bright, slow-moving meteors. Its radiant is located near the Pleiades.

November 16-17 Leonids

Normally a minor shower, the Leonid display is famous for its periodic storms. Short-lived bursts in activity have occurred in recent years.

December 13-14 Geminids

The most impressive annual shower, with a typical hourly rate of 60-80 meteors, it often gets overlooked because people are unwilling to brave the nighttime cold during this time of year. This shower is unique because its meteors are derived from an asteroid (3200 Phaeton) rather than a comet.

December 21-22 Ursids

Another overlooked shower, the Ursids are preempted by the holiday season. Those who take the time to check out the Ursids will see 15-20 meteors per hour radiating from the Little Dipper.
