❓ why

Why do meteor showers appear at the same time every year?

Quick Answer

Earth crosses the same stream of debris along its orbit each year. When those tiny particles burn up in our atmosphere, we see a recurring meteor shower.

The Full Story

Meteor showers happen when Earth passes through dust and debris left behind by comets or, in some cases, asteroids. The debris is spread along a stable orbital path, so the shower occurs at roughly the same date each year. Famous examples include the Perseids in August and the Geminids in December. The Perseids are linked to comet Swift-Tuttle, while the Geminids are associated with asteroid 3200 Phaethon.

Key Facts

1.The Perseids peak around August each year
