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 .
Those currently can monitor the sky at most every night, and therefore miss most of the smaller asteroids which are bright enough to detect for less than a day. Such very small asteroids much more commonly impact Earth than larger ones, but they make little damage. Missing them therefore has limited consequences. Much more importantly, ground ...

Four huge asteroids — and a fifth that's much smaller — are passing Earth on Thursday in their closest approaches to the planet ever recorded. 4 large asteroids, including 1 the size of a ...
The asteroid also won't hit our planet when it makes another close approach in 2036. ... Apophis was initially identified as one of the most hazardous asteroids that could impact Earth after its ...
The 15-kilometer-wide meteorite hit land to make the 150-kilometer-wide Chicxulub crater and in the process, wiped out most dinosaurs, mammals, and marine and avian reptiles (although volcanic ...
In April 2018, the B612 Foundation reported: "It's 100 percent certain we'll be hit [by a devastating asteroid], but we're not 100 percent certain when." [ 10 ] Also in 2018, physicist Stephen Hawking considered in his final book Brief Answers to the Big Questions that an asteroid collision was the biggest threat to the planet.
The critical one is in 2032, on the 22nd of December, somewhere around the middle of the day in Universal Time. That is when the asteroid is passing, really, through a part of the orbit of the Earth.
