This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of January 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors . Asteroid.
247 Eukrate. Eukrate ( minor planet designation: 247 Eukrate) is a rather large main-belt asteroid. It is dark and probably a primitive carbonaceous body. The asteroid was discovered by Robert Luther on March 14, 1885, in Düsseldorf. It was named after Eucrate, a Nereid in Greek mythology . In 2001, the asteroid was detected by radar from the ...
The largest asteroid to pass within 1 LD of Earth in 2019 was 2019 OK with an estimated diameter of around 95 meters and an absolute magnitude of 23.3. The fastest asteroid to pass within 1 LD of Earth in 2019 was 2019 FC1 that passed Earth with a velocity with respect to Earth of 25.9 km/s (58,000 mph).
Below is an example list of near-Earth asteroids that nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2023. During 2022, over 1,000 asteroids passed within 10 LD (3.8 million km) of Earth. Rows highlighted grey indicate a planet or main-belt asteroid
Two asteroids, 2022 EB 5 and 2022 WJ 1, are noteworthy in that both were detected before impacting Earth. 2022 EB 5 and 2022 WJ 1 are the 5th and 6th successfully predicted impacts in history, respectively. The latter also holds the record for the smallest asteroid discovered while in space, with an estimated diameter less than 1 metre (3.3 ft ...
The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA, 2019 MO, 2022 EB 5, 2022 WJ 1, 2023 CX 1 and 2024 BX 1 are the only eight asteroids discovered before impacting into Earth (see asteroid impact prediction ). Scientists estimate that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance closer than ...
Lowell Observatory Near-Earth-Object Search. / 35.2028°N 111.6644°W / 35.2028; -111.6644. Lowell Observatory Near-Earth-Object Search ( LONEOS) was a project designed to discover asteroids and comets that orbit near the Earth. The project, funded by NASA, was directed by astronomer Ted Bowell of Lowell Observatory in Flagstaff, Arizona.
The number of asteroids brighter than H = 25, which corresponds to about 40 m (130 ft) in diameter, is estimated at 840,000 ± 23,000 —of which about 1.3 percent had been discovered by February 2016; the number of asteroids brighter than H = 30 (larger than 3.5 m (11 ft)) is estimated at 400 ± 100 million—of which about 0.003 percent had ...
