A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2012, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1]
The largest asteroid to pass within 1 LD of Earth in 2021 was 2021 SG with an estimated diameter of around 68 meters and an absolute magnitude of 24.0. The fastest asteroid to pass within 1 LD of Earth in 2021 was 2021 UA 7 that passed Earth with a velocity with respect to Earth of 27.7 km/s (62,000 mph). [2] [note 2]
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 of these objects are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
The location of 2024 YR4 qualifies it not just as any asteroid, but a near-Earth object (NEO). NEOs are defined as asteroids that hug the inner solar system, where we live, coming within 1.3 ...
The asteroid, described as "very small" by NASA, impacted Earth's atmosphere around 11:14 a.m. ET and created a fireball over eastern Russia, the space agency said in a post on X.
The chances of asteroid 2024 YR4 colliding with Earth in 2032 hit a record high. ... 2.7% chance of collision once associated with an asteroid discovered in 2004 called Apophis, making 2024 YR4 ...

1950 DA made distant approaches to Earth on 20 May 2012, 5 February 2021 and 5 February 2023. [18] However, at these times it was a quarter to half an AU away from Earth, preventing more useful astrometrics and timing that occurs when an object is closer to Earth. The next close approach that presents a good opportunity to observe the asteroid ...
