The Perseid Meteor Shower is a yearly event that begins in late summer. This year, they will peak around August 11th and 12th, although they will last about two weeks before and after the peak. They are associated with the comet Swift Tuttle.
These meteors are very small, usually the size of a grain of sand or a pebble. they pose no threat to Earth. The only reason we care about them at all is the pretty trails they make as they enter the atmosphere. These trails have been noticed for at least two millennia, and have fascinated people the world over.
If you like shooting stars, this weekend will have some fantastic viewing opportunities. Make a wish!
