The Perseids typically peak in mid-August every year, when the Earth intersects with the trail of Comet Swift-Tuttle. Debris from the comet impacts the Earth’s atmosphere and streaks across the sky, creating shooting stars.
Typically, the Perseids’ peak features about 100 meteors per hour. But this year, we may see twice that many thanks to an “outburst,” which occurs when the Earth runs into leftover debris from past orbits of the comet as well as debris from the current year. The extra material combines to create a truly spectacular meteor shower.
This year, the Perseids are expected to contain meteors from comet trails laid down in 1862, 1479, and 1079. This means that some of the meteors that will impact Earth’s atmosphere next week broke off from the Comet Swift-Tuttle nearly a thousand years ago.
If you’re planning to watch the Perseids, it’s best to be prepared. The optimal time to see the meteor shower is from late at night on Thursday August 11 to early Friday morning on the 12th, before sunrise. Be sure to get plenty of rest if you’re going to stay up late to watch the show.
Pick a spot that’s far away from city lights that brighten the sky. The darker the sky, the better the viewing, so you may have to drive into the countryside. This tool can help you find a dark sky location nearby. Remember to give your eyes at least 20 minutes to adjust to the dark.
