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]
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.
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.
The closest approach to Earth occurred on 4 April 2019, when it approached to a distance of 13,104 km (8,142 mi). [6] [c] The final close approach in 2020 occurred on 13 February 2020 at a distance of about 41,000 km (25,000 mi) from Earth's surface. [25] The orbital period of 2020 CD 3 around Earth ranged from 70 to 90 days.
2020 BX 12 was discovered on 27 January 2020 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at the Mauna Loa Observatory in Hawaii.The ATLAS survey was designed for detecting near-Earth asteroids on approach to Earth, particularly those that may be considered potentially hazardous under circumstances where they can approach Earth from close distances.
A small asteroid was visible in northern Siberia on Tuesday, as it closed in on its collision course with Earth. The European Space Agency issued an alert for the 27-inch asteroid at 4:27 a.m. ET ...
2020 HS 7 is a very small asteroid classified as a near-Earth object of the Earth-crossing Apollo group.When it was discovered by the Pan-STARRS 2 survey on 27 April 2020, the asteroid was initially calculated to have a 10% chance of impact with Earth before being ruled out by improved orbit determinations from additional observations.
