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 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]
An asteroid the size of a small truck will pass by Earth tonight, making one of the closest approaches to the planet ever recorded. Asteroid 2023 BU will zoom over the southern tip of South ...
The asteroid was found to have a rapid rotation by the Magdalena Ridge Observatory's 2.4-meter telescope. It rotates at an extremely rapid rate of 24.5 seconds. 2010 JL 88 is the second fastest natural rotating object discovered in the Solar System, [8] after 2014 RC, which has a period of 16 seconds but still an uncertain period solution.
It's an asteroid, first spotted by an observatory in White Sands, New Mexico. Astronomers estimate On Jan. 26, you might be able to see 2004 BL86 skim past Earth.
An asteroid between 130 and 300 feet wide has a slight chance of hitting Earth in 2032 — but the precise odds have been a moving target since the space rock was first detected nearly two months ago.
The fastest asteroid to pass within 1 LD of Earth in 2024 was 2024 CH 4 that passed Earth with a velocity with respect to Earth of 24.01 km/s (53,700 mph), [4] while the slowest bypass within lunar distance was that of 2024 VO at a velocity with respect to Earth of 3.08 km/s (6,900 mph). [5]
