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. Objects coming from the ...
During 2022 about 124 asteroids passed within 1 LD of Earth. 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. For reference, the radius of Earth is about 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances.
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
According to NASA, 132 known asteroids have passed closer to Earth than the moon is since October 2023. Overall, there have been upward of 36,000 asteroid fly-bys, the agency reported.
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 ...
A number of known asteroids came closer than this in 2020, notably 2020 CW, 2020 JJ, 2020 QG, and 2020 VT 4 which all approached Earth within 0.05 lunar distances. Two objects have been observed to be temporary satellites of Earth: 2020 CD 3 in February 2020 and 2020 SO in September 2020, albeit the latter has been confirmed to be a rocket ...
These are asteroids in a near-Earth orbit without the tail or coma of a comet. As of March 2024, 34,603 near-Earth asteroids (NEAs) are known, 2,406 of which are both sufficiently large and may come sufficiently close to Earth to be classified as potentially hazardous. [1] NEAs survive in their orbits for just a few million years. [27]
