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.
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 .
A meteor that exploded in a spectacular fireball over Niagara Falls in 2022 was the smallest asteroid ever measured, a new study has found.. The asteroid, spotted by astronomers just hours before ...
"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said. A massive asteroid has a chance to hit Earth.
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]
On Sunday, another asteroid about half the size of 2008 OS7 will pass within 4.5 million miles of Earth. The closest recorded asteroid flyby happened in August of 2020, when a space rock roughly ...
Three years later, in 2012, the 40 meter diameter asteroid 367943 Duende was discovered and successfully predicted to be on close but non-colliding approach to Earth again just 11 months later. This was a landmark prediction as the object was only 20 m × 40 m , and it was closely monitored as a result.
