Will an asteroid ever hit Earth? Good news: There are no known asteroids that pose any threat, BUT tiny, harmless meteors burn up in Earth’s atmosphere all the time – you probably know them better as shooting stars!
Our asteroid expert Dr. Kelly Fast explains that as they disintegrate in the atmosphere, they can create beautiful meteor showers in the night sky. Impacts that affect the Earth’s surface are rare, and happen on timescales of hundreds, to thousands, to millions of years.
