An animation of 2008 TC3's excited rotation prior to entering the atmosphere. The asteroid was discovered by Richard A. Kowalski at the Catalina Sky Survey (CSS) 1.5-meter telescope at Mount Lemmon, north of Tucson, Arizona, US, on October 6, 06:39 UTC, 19 hours before the impact.
The NASA commitment has resulted in the funding of a number of NEO search efforts, which made considerable progress toward the 90% goal by the target date of 2008 and also produced the first ever successful prediction of an asteroid impact (the 4-meter 2008 TC 3 was detected 19 hours before impact).
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, 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.

On 7 October 2008, an approximately 4 meter asteroid labeled 2008 TC 3 was tracked for 20 hours as it approached Earth and as it fell through the atmosphere and impacted in Sudan. This was the first time an object was detected before it reached the atmosphere and hundreds of pieces of the meteorite were recovered from the Nubian Desert .
This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
Jilin bolide. The 2nd largest meteorite fall of the 20th century (after the Sikhote-Alin event). A fireball larger than the full moon was seen. There were several explosions then a violent breakup. [44] It yielded a piece at 1770 kg, more than twice the Chelyabinsk meteorite (654 kg), and total fragments collected was about 4 tons. [45] 1984 ...
The Orconuma meteorite fell to Earth on March 7, 2011, in Orconuma, Bongabong, Oriental Mindoro. [2] It was discovered by three farmers, Fredo Manzano, Edgar Francisco Sr., and Enrico Camacho, Jr., who found the meteorite in the middle of a field. [3] The three farmers initially hid and stored the specimen before publicizing their discovery in ...
