The best meteor shower of the year is here, NASA says. The Perseid meteor shower has already started bracing the sky from July 17 and will be here until August 24, 2021. The best time to view the shower, though, is between August 11 and August 12, where there could be up to 100 visible meteors per hour, according to NPR.
The annual meteor shower is caused by the 109PSwift-Tuttle comet that is in a 133-year orbit around the sun before reaching beyond Neptune, leaving debris behind, according to Popular Science.
