There are 1620 near-Earth asteroids listed in the risk table and 37,736 virtual impact dates, so for each asteroid in the risk table, there is an average of about 23 virtual impact dates. Only about 19 objects in the table are large enough, with a diameter greater than about 140 meters, to be considered potentially hazardous objects. The ...
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 .
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.
The small asteroid, measuring about a metre across, did not pose a threat to life. It was the third space rock detected imminently before impacting the Earth this year, but only the tenth on record.
The chances that a near-Earth object, such as a comet or asteroid, could impact Earth is the subject of the Torino Scale and Palermo Scale. Near-Earth objects that are actively listed at the Sentry Risk Table or NEODyS should be individually included in this category. The generic category of "Potentially hazardous asteroids" is included merely ...

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 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.
