    Default Asteroid Enters Earth Atmosphere

    It hit the ground in Africa. Where will the next one hit? Now they can predict this.

    Small asteroid headed for light show over Africa
    By SETH BORENSTEIN – 1 day ago Associated Press

    WASHINGTON (AP) — A small asteroid was headed for a fiery but harmless dive into Earth's atmosphere early Tuesday morning over Africa, astronomers said in a first of its kind advance warning.

    Harvard scientists announced late Monday afternoon that the asteroid 2008 TC3 would burn up in the sky, making a fireball potentially visible to people in northern Africa. Measuring between 3 feet and 15 feet in diameter, the rock was expected to enter Earth's atmosphere above Sudan at 10:46 p.m. EDT Monday, just before dawn in Africa.

    Harvard astronomer Tim Spahr said the asteroid was so small it wouldn't reach the ground before burning up and wouldn't hurt anyone, but the fireball should be seen heading from west to east.

    "It's the first time we've been able to predict an impactor in advance and it'll be quite a celestial show for the world," said Donald Yeomans, manager of NASA's Near Earth Object program, which tracks asteroids and comets that come close.
    There are 5,681 such objects, but only 757 of them are large enough to cause any damage if they hit Earth.
    This object, spotted by an Arizona telescope late Sunday and calculated on Monday to be heading toward Earth, isn't one of them. Astronomers don't know precisely how big it is or what it is made of, but they know that it is small enough that it will burn up harmlessly. As it enters the atmosphere becoming a meteor, it compresses the air in front of it, which then gets hotter, causing a fireworks display.

    Rocks this size hit Earth's atmosphere about two or three times a year, but without warning, Yeomans said.

    Astronomers were only able to give the world about six hours notice because the rock is so dark and small. It was spotted a little farther away from Earth than the moon, said Spahr, director of the International Astronomical Union's Minor Planet Center. Astronomers hope by scanning the sky they can eventually give Earth warning for more worrisome rocks that come this way.
    "If this were something larger and it was going to hit the ground we would be able to get people out of the way," Spahr said. But with something this size, they can tell people to look up for a sight that could be "pretty cool from the ground," he said.

    I loved going to strip clubs; I actually made some friends there. Now things are different for the clubs and for me. As a result I am not as happy.

    Customers are not entitled to grope, disrespect, or rob strippers. This is their job, not their hobby, and they all need income. Clubs are not just some erotic show for guys to view while drinking.

    Here's the significance of this post....

    "It's the first time we've been able to predict an impactor in advance and it'll be quite a celestial show for the world,"...Astronomers were only able to give the world about six hours notice because the rock is so dark and small.
    Guess we'd better listen to news more closely if we want to get out of the way. Fortunately it doesn't happen that often.
