A small, newly-discovered asteroid named 2008 TC3 is approaching Earth and chances are good that it will hit. Steve Chesley of JPL estimates that atmospheric entry will occur on Oct 7th at 0246 UTC over northern Sudan [ref]. 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. Odds are between 99.8 and 100 percent that the object will encounter Earth, according to calculations provided by Andrea Milani of the University of Pisa. [ephemeris] [3D orbit]
