 | First Predicted-to-Impact Asteroid Hits the Earth Posted by Ted Keer on 10/07, 6:12pm | |
| INCOMING ASTEROID: A small, newly-discovered asteroid named 2008 TC3 is approaching Earth and chances are better than 99.8% that it will hit. Steve Chesley of NASA's Jet Propulsion Laboratory estimates that atmospheric entry will occur on Oct 7th at 0246 UTC over northern Sudan to the Red Sea. Measuring only a few meters across, the space rock poses no threat to people or structures on the ground, but it should create a spectacular fireball, releasing about a kiloton of TNT in energy as it disintegrates and explodes in the atmosphere. Asteroids of this size hit Earth every few months, but this is the first time one has been discovered before it hit. | ||
