Asteroid Explodes Over Sudan

radioweather writes "A recently discovered Apollo Asteroid, 2008 TC3, exploded over Sudan at about 1046 EDT on October 7, 2008, according to astronomer Tim Spahr of Harvard University 2008 TC3 was discovered on Monday by an observer at the Mt Lemmon Observatory near Tucson, Arizona. 2008 TC3 is notable in that it is the first Asteroid of its size that was identified before impact and tracking it put the entire Spaceguard tracking system to an extreme test. TC3 is estimated to be only two to five meters in diameter but exploded with the force of a one kiloton of explosive power." We mentioned the asteroid last on Monday, when it was only at a 99.8 percent chance of colliding with Earth.

    [pedantic] you mean a 99.8 chance of colliding with Earth's atmosphere. [/pedantic]
    From Slashdot's previous summary:

    The asteroid is assumed to be 3-4 meters in size; it is expected to burn up completely in the atmosphere, causing no harm

      Anyone know how big a rock needs to start off to survive the passage thru the atmosphere and have any part of itself hit the ground??

      Size doesn't matter (thank you. thank you. Tip your waitress). No, really. It matters, it just isn't "all" that matters. Relative velocity is just as important. If the body sneaks up on us from behind, it could actually have a relatively low differential velocity. The nickel-iron sample you found would probably fit in that category, and it slowed to terminal velocity before being burned up.

      An extremely large body coming directly at us for a head-on collision probably wouldn't make it to the ground (and wouldn't have to in order to take out a large percentage of life in our little gravity well hole.)

      All true... tho I suppose someone somewhere has run the numbers for the basic classes of "speed + direction + mass + velocity + composition + fudge factor" vs. "size of hole in ground, or velocity and vectors of remaining chunks of planet". ;)

      I always wondered how that little chunk of iron wound up sitting on *top* of the grass, like it had been gently placed there... tho I've read that isn't too unusual with small meteorites.

    Over.

    It completely burned up miles above the surface. That quote is like saying "Drakin020 had a birthday party with cake! No deaths have been reported yet." In other words, it's purely sensationalism. Though it is a true statement, no deaths will *ever* be reported due to this event, because none occurred.

      Because the asteroid was itentified and tracked days before it entered the atmosphere. For the first time, astronomers were able to predict the exact time and location the asteroid would strike (well, would have stuck if it hadn't exploded in the atmosphere). Also, what we see as shooting stars are little more than grains of sand, this was more like a good sized boulder and would have made a noticable fireball as it tracked across the sky.

    This spore-laden asteroid was only a followup, a redundant backup mission. The original alien spore mission to Sudan succeeded several years ago ... spore-infected individuals are known to take up weapons and form militia groups who then engage in rape, murder, and genocide. So far nobody outside Sudan seems to have taken much notice or to care.

However, I am presently unable to eradicate them. If you could wire a sum of $10,000 (ten thousand dollars) to my account then I will be able to take action. I am an official in the Sudanese government, and can guarantee that your expendature will be reimburesed plus an additional $10,000 reward, but it operates slowly and the government funds will not be available in time.
