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 .
According to the latest calculations from NASA's Jet Propulsion Laboratory, there is a 1.6% chance the asteroid will strike Earth on December 22, 2032. The asteroid 2024 YR4 is now rated at Level ...
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 ...
