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.

A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7 percent chance of striking Earth in 2029. Further observations ruled out an impact. "City killer ...
The other, called Vallis Schrödinger, is about 168 miles (270 km) long and 1.7 miles (2.7 km) deep. The impact occurred during a period of heavy bombardment in the inner solar system by space ...
On October 6, 2008, while observing with the CSS 1.5 meter (60") telescope at Mount Lemmon Observatory, he discovered 2008 TC 3. Approximately 20 hours after its discovery this asteroid entered the Earth's atmosphere over Sudan, becoming the first asteroid discovered before impact with the earth. [4] Kowalski was honored with a small piece of ...
The asteroid, called 2024 UQ, was first spotted on 22 October by the Asteroid Terrestrial Impact Last Alert System, or ATLAS, a telescope network scanning the sky for space rocks likely headed for ...
Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
