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 .
Double asteroid with two nearly equal components; its double nature was discovered using adaptive optics in 2000 92 Undina: 126: 1867 July 7: Created in one of the largest asteroid-on-asteroid collisions of the past 100 million years 216 Kleopatra: 217×94: April 10, 1880: Metallic asteroid with "ham-bone" shape and 2 satellites 243 Ida: 56×24×21

There is a roughly 1-in-2700 chance of such a collision in 2182, and the Earth is hit by similar-sized asteroids about every 100-200 thousand years. ... ‘Climatic and ecological responses to ...
We are aware of a recent example in history where this has happened. It was 1908 in Siberia. There was an event where 2,000 square kilometers of forest had been flattened by a big explosion, high ...
The European Space Agency previously said the asteroid was "spotted on a collision course with Earth," and that it was about 70 centimeters, or about 27 1/2 inches, in diameter.
These features were caused by the collision of meteors (consisting of large fragments of asteroids) or comets (consisting of ice, dust particles and rocky fragments) with the Earth. For eroded or buried craters, the stated diameter typically refers to the best available estimate of the original rim diameter, and may not correspond to present ...
In April 2018, the B612 Foundation reported: "It's 100 percent certain we'll be hit [by a devastating asteroid], but we're not 100 percent certain when." [10] Also in 2018, physicist Stephen Hawking considered in his final book Brief Answers to the Big Questions that an asteroid collision was the biggest threat to the planet.
