This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024 [update] , all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors .
The impact site was not examined by scientists until 20 years later, when they discovered the asteroid carved a massive area of destruction of around 830 square miles, according to NASA.
