Satellites in geostationary orbit. From the list in the first section, these are the closest known asteroids per year that approach Earth within one lunar distance.More than one asteroid per year may be listed if its geocentric distance [note 1] is within a tenth of the lunar distance, or 0.10 LD.
An example list of near-Earth asteroids that passed more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2008. 2007 TU 24 (~250 meters in diameter) passed 1.44 LD (554,000 km) from Earth on January 29, 2008. 2008 CE 22 (~18 meters in diameter) passed between 0.9997 and 1.0023 LD (384,300 to 385,300 km) from Earth on February 6, 2008.
The largest asteroid to pass within 1 LD of Earth in 2022 was 2022 TM 2 with an estimated diameter of around 39 meters for an absolute magnitude of 25.2. The fastest asteroid to pass within 1 LD of Earth in 2022 was 2022 YW 6 that passed Earth with a velocity with respect to Earth of 29.8 km/s (67,000 mph). [2] [note 1]
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 .

2022 OB 5 is a small near-Earth asteroid that passed within 0.00679 AU (1,016,000 km) from Earth on 5 August 2022. [2] It is the primary target of AstroForge 's Brokkr-2 (Odin) mission, which is planned for launch alongside IM-2 by February 2025, reaching the asteroid around December 2025. [ 3 ]
Due to its Earth-like orbit, the object might be of artificial origin or lunar ejecta. [1] However, visible spectroscopy obtained with the Gran Telescopio Canarias shows that it is an asteroid. [9] The closest approach to Earth in 2022 was 26 June 2022 at roughly 812,200 km (504,700 mi) when it had a relative velocity of 0.96 km/s (2,100 mph). [3]
A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2023. [1] As most asteroids passing within a lunar distance are less than 40 meters in diameter, they generally are not detected until they are within several million km of Earth. Objects coming from the ...
