This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024 [update] , 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 .

The asteroid's provisional designation as a minor planet, "2024 YR 4", was assigned by the Minor Planet Center when its discovery was announced on 27 December 2024. [2] 2024 indicates the discovery year, the first letter, "Y", indicates that the asteroid was discovered in the second half-month of December (16 to 31 December) of that year, and "R 4" indicates that it was the 117th provisional ...
Update: The odds of asteroid 2024 YR4 striking Earth in 2032 have fallen to 1.5%, NASA announced Wednesday. Read the latest.. The risk that an increasingly ominous asteroid dubbed 2024 YR4 will ...
An asteroid that measures up to 300 feet across could smack into Earth in 2032, and while NASA says the chances of a collision are “extremely low,” the probability has been increasing since ...
An asteroid capable of flattening a mid-sized city could potentially collide with Earth eight years from now, as its orbit around the sun briefly intersects the path of our planet. Named 2024 YR4 ...
Stony asteroids with a diameter of 4 meters (13 ft) enter Earth's atmosphere about once a year. [22] Asteroids with a diameter of 7 meters enter the atmosphere about every 5 years with as much kinetic energy as the atomic bomb dropped on Hiroshima (approximately 16 kilotons of TNT), but the air burst is reduced to just 5 kilotons. [22]
The yellow dots show the position uncertainty of asteroid 2024 YR4 when it encounters Earth in 2032, based on observations up to January 31, 2025.
