One of the brightest meteor showers of the year happens overnight. It’s called the the Perseid meteor shower and although it happens for several days, it will peak around 3 a.m. Saturday.
The meteor showers happen as the Earth makes its annual trip around the sun and encounters a particular trail of comet dust.
Sally Oey is an associate professor of astronomy at the University of Michigan. She says as the Earth travels through this comet dust, little particles enter our Earth’s atmosphere and appear as meteors or “shooting stars.”
