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.
A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2023. [1] As most asteroids passing within a lunar distance are less than 40 meters in diameter, they generally are not detected until they are within several million km of Earth.
Asteroid close approaches to Earth in 2024 include: Asteroid Perigee Date in 2024 2009 JV 1: 0.0571 AU (19.21 LD) January 5 2021 BL 3: 0.0441 AU (17.16 LD) January 23 [1]
Four large asteroids will make their closest approaches to Earth on Thursday, each passing by the planet within a 24-hour time frame. Two had already zipped past early in the morning, according to ...
An asteroid roughly the size of a skyscraper will pass close by Earth on Friday, but there's no risk of it hitting the planet. NASA’s Center for Near Earth Object Studies estimates that the ...
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 ...
Below is an example list of near-Earth asteroids that passed or nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2022. During 2021 over 1000 asteroids passed within 10 LD (3.8 million km) of Earth.
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]
