In 2022, NASA launched the Double Asteroid Redirection Test (DART) spacecraft, whose sole goal was to fly 7 million miles to the 525-foot asteroid Dimorphos, and crash into it at 14,000 miles per ...
99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.

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 .
2024 YR 4 is an asteroid that is classified as an Apollo-type (Earth-crossing) near-Earth object, with an estimated diameter of 40 to 90 metres (130 to 300 ft).As of 19 February 2025, it has a rating of 3 on the Torino scale, with a 1-in-67 (1.5%) chance of impacting Earth on 22 December 2032, [7] and a rating of −0.51 on the Palermo scale, corresponding to an impact hazard 31% of the ...
The European Space Agency in January placed the asteroid's odds of hitting Earth at roughly 1%, before NASA's Jet Propulsion Laboratory estimated the risk was more like 1.6% at the tail end of the ...
The minimum orbit intersection distance (MOID) between an asteroid and the Earth is the distance between the closest points of their orbits. This first check is a coarse measure that does not allow an impact prediction to be made, but is based solely on the orbit parameters and gives an initial measure of how close to Earth the asteroid could ...
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.
