Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
2024 UQ, designated formerly as A11dc6D, was a one-meter meteoroid that struck the Earth's atmosphere and burned up harmlessly on 22 October 2024 above the Pacific Ocean off the coast of California. 2024 UQ is the tenth impact event that was successfully predicted, which was discovered by the ATLAS survey.
The soonest virtual impactor of an asteroid larger than 50 meters in diameter with a better than 1:1-million chance of impact is 2022 PX 1 on 11 August 2040 with a 1: 330 000 chance of impact. [8] It is estimated to be 120-meters in diameter, has a short observation arc of 3.1-days, and is expected to be 1.78 AU (266 million km ) from Earth on ...
In this dramatic illustration, a meteor falls toward Earth from space. A pair of asteroids that rammed into Earth more than 35 million years ago seemingly had no climate impacts, scientists said ...
The impact of a large asteroid – Hirata's computer simulations suggest the asteroid measured 186 miles in diameter – could cause the moon to shift to its current position, he suggests.
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 .
In 2021, evidence for a probable impact 3.46 billion-years ago at Pilbara Craton has been found in the form of a 150 kilometres (93 mi) crater created by the impact of a 10 kilometres (6.2 mi) asteroid (named "The Apex Asteroid") into the sea at a depth of 2.5 kilometres (1.6 mi) (near the site of Marble Bar, Western Australia).

The Double Asteroid Redirection Test will knock an asteroid out of orbit, effectively sacrificing itself. NASA’s Asteroid-Clobbering System Make Impact on Monday. Here’s How to Watch
