How Meteor Showers Form
Meteor showers happen when Earth's orbit carries it through a trail of debris left behind by a comet or asteroid; that debris burns up brightly from friction with the atmosphere. Because Earth passes through the same trail at roughly the same time each year, each shower repeats on a predictable annual schedule.
A Few Tips for Watching
Meteor showers cover a wide swath of sky, so the naked eye actually works better than a telescope. Getting away from city lights, waiting for your eyes to adjust to the dark, and checking the moon phase all make a real difference in how many meteors you catch.
Frequently Asked Questions
Do I need special equipment to see a meteor shower?
No β because you need to watch a wide area of sky, your unaided eyes work better than a telescope, which narrows your field of view too much.
Can you see meteor showers from a city?
You can, but light pollution means only the brightest meteors will be visible and only rarely. The farther you get from city lights, the more meteors you'll be able to spot.
