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.
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, 13 April 2029.
The Chelyabinsk meteor is thought to be the biggest natural space object to enter Earth's atmosphere since the 1908 Tunguska event, [23] [24] [25] and the only one confirmed to have resulted in many injuries, [26] [Note 1] although a small number of panic-related injuries occurred during the Great Madrid Meteor Event of 10 February 1896.

The largest asteroid to pass within 1 LD of Earth in 2020 was 2020 LD with an estimated diameter of around 145 meters and an absolute magnitude of 22.4. The fastest asteroid to pass within 1 LD of Earth in 2020 was 2020 FD 2 that passed Earth with a velocity with respect to Earth of 33.4 km/s (75,000 mph). [2] [note 3]
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 ...
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 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 ...
