Based on the few successfully predicted asteroid impacts, the average time between initial detection and impact is currently around 9 hours. There is however some delay between the initial observation of the asteroid, data submission, and the follow-up observations and calculations which lead to an impact prediction being made.
List of predicted asteroid impacts on Earth. This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of January 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 ...
The largest asteroid to pass within 1 LD of Earth in 2022 was 2022 TM2with an estimated diameter of around 39 meters for an absolute magnitudeof 25.2. The fastest asteroid to pass within 1 LD of Earth in 2022 was 2022 YW6that passed Earth with a velocity with respect to Earth of 29.8 km/s (67,000 mph). [2][note 1] Two asteroids, 2022 EB5and ...
NASA's Sentry System continually scans the MPC catalog of known asteroids, analyzing their orbits for any possible future impacts. [115] Currently none are predicted (the single highest probability impact currently listed is ~7 m asteroid 2010 RF 12, which is due to pass earth in September 2095 with only a 5% predicted chance of impacting).

Piszkéstető Stn. 2022 EB5 was a small, two-metre Apollo near-Earth asteroid that disintegrated in Earth's atmosphere at 21:22 UTC on 11 March 2022, over the Arctic Ocean southwest of the Norwegian island Jan Mayen. With an atmospheric entry speed of 18 km/s (11 mi/s), the asteroid's impact generated a 4-kiloton-equivalent fireball that was ...
The ESA’s Hera mission will launch a spacecraft in October on a journey to observe the aftermath of the DART impact, reaching the asteroid pair near the end of 2026. Together with a pair of ...
99942 Apophis (provisional designation 2004 MN4) is a near-Earth asteroid and a potentially hazardous object with a diameter of 370 metres (1,210 feet) [ 3 ] that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
The asteroid brightened to about apparent magnitude 15 (about the brightness of Pluto) before disappearing into Earth's shadow. [1] It is the sixth successfully-predicted asteroid impact. [8] [c] With an absolute magnitude of 33.6, it is the smallest asteroid discovered while it was in space. [13]
