If you can catch only one meteor shower this year, it should be the Perseids. They're zipping across the sky right now, and will peak overnight on Aug. 11-12 and Aug. 12-13. Weather conditions permitting, this year's show should be spectacular during the peak dates because the moon will only be a slim sliver of a crescent and won't interfere with the blazing glory of the Perseids.

In normal years, the Perseids produce about 60-70 meteors an hour, and they're typically rich in fireballs. In outburst years, such as 2016, the rate can more than double to around 150 to 200 meteors an hour. NASA meteor expert Bill Cooke says outlandish claims often accompany reports of celestial events, including one last year that the Perseids would be the "brightest shower in recorded human history" and that meteors could be visible during the day.

But that shouldn't dim your meteor-watching plans at all.

While both nights of the peak will be spectacular, look to Aug. 12-13 for the best meteor shower of 2018, Cooke said. The meteors begin flying after midnight and continue into the predawn hours.

"This year the moon will be near new moon, it will be a crescent, which means it will set before the Perseid show gets underway after midnight," Cooke told Space.com. "The moon is very favorable for the Perseids this year, and that'll make the Perseids probably the best shower of 2018 for people who want to go out and view it."

The Perseids, which run annually from July 17-Aug. 24, are produced as the Earth passes through dust left behind by the comet Swift-Tuttle, discovered in 1862. The peak occurs when the Earth passes through the densest, dustiest area. The pieces of debris heat up as they enter the Earth's atmosphere and burn in a bright burst of light as they travel across the sky at about 37 miles per second. Most of the meteors are about the size of a grain of sand, so there's little chance one will make it down to Earth as a meteorite.
