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, 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.
If the distance between the asteroid and the centre of the Earth is less than Earth radius then a potential impact is predicted. To take account of the uncertainties in the orbit of the asteroid, many future projections are made (simulations) with slightly different parameters within the range of the uncertainty.
Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
An asteroid called 2020 CD3 was bound to Earth for several years before leaving the planet's orbit in 2020 and another called 2022 NX1 became a mini-moon of Earth in 1981 and 2022 and will return ...
The asteroid, called 2024 UQ, was first spotted on 22 October by the Asteroid Terrestrial Impact Last Alert System, or ATLAS, a telescope network scanning the sky for space rocks likely headed for ...
Asteroid close approaches to Earth in 2024 include: Asteroid Perigee Date in 2024 2009 JV 1: 0.0571 AU (19.21 LD) January 5 2021 BL 3: 0.0441 AU (17.16 LD) January 23 [1]
[note 1] The largest asteroid on this list that is risk–listed is 2023 SM 5 at about 17 meters in diameter with a 3.5-day observation arc and a 1: 91 000 chance of Earth impact on 2118 September 24. [3] For reference, the radius of Earth is about 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances.
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 ...
