❓ why
Why do meteor showers happen at the same time every year?
Quick Answer
Earth passes through the debris left by comets or asteroids on the same orbital path each year.
The Full Story
Meteor showers are caused when Earth crosses a stream of dust and small particles left behind by a comet or, less often, an asteroid. Because Earth repeats the same orbit around the Sun every year, the encounter happens at about the same time on the calendar. These particles burn up in the atmosphere and create streaks of light called meteors. The Perseids, for example, are associated with debris from Comet Swift-Tuttle.
Key Facts
1.Earth completes one orbit in about 365 days
2.Perseids come from Comet Swift-Tuttle
3.Meteors burn up in Earth’s atmosphere
