Deadly asteroid headed for earth (poll)

[Alreiger]

That's about 0.06 km if I'm not mistaken. How fast is this object going, though? They always include the size to make it seem dangerous, but something this size wouldn't be a world wide concern unless it managed to strike a speed that unleashed incredible amounts of force. (Example: The largest nuclear weapon ever dropped [Tsar Bomba] released 50 megatons, while the Chicxulub asteroid [the one that might have wiped out the dinosaurs] hit at around 90 teratons.) If this is truly comparable to the Tunguska event, it won't be a doomsday scenario if that's what some of you are thinking. It's disappointing to see people scared of something like this, it's like Comet Elenin, people were so worried, even after it had broken apart. But a majority of articles made about it were hyped up to make a rock that could pass by us harmlessly or leave a small dent on our massive planet, sound like it could be a threat to everyone.

But then again, I might just be an idiot.
