As big as a small hill. I am reading an interesting article right now. Its called " 5 irrational Fears even rational people have". Place 5 was Swine Flu. Place 4 is Killer Asteroids. I didnt come any further yet. Here a quote: "To be ranked as a planet killer, an asteroid has to be pegged as a 10 on the Torino Impact Hazard Scale. Currently, scientists can only find one asteroid near Earth that ranks even a one on that scale, never mind a 10. Everything else is a zero." The Article so far hasnt told me anything new. But its written in an entertaining manner. Here the link maybe you should read it: http://www.cracked.com/article/158_5-irrational-fears-even-rational-people-have/?wa_user1=3&wa_user2=Weird+World&wa_user3=article&wa_user4=recommended I am not saying ther cant be a rock doing damage but the effects wont be threatening to humanity. The telescopes/abilities of the Nasa/ESA are getting better and better they increase even faster then Cpu Power. We can rule out total destruction in 2012 and a small Asteroid really hitting earth in 2012 is unlikely. |
First, The Torino Impact Hazard Scale. This scale don't measure the chance of being by a certain asteroid or the likelihood of being hit by one, it only ranks the already known asteroids in categories.
Second, If you don't know something, you can't know if it's dangerous or not, so talking about the known asteroids near Earth is not that reassuring. And, while those asteroids may not be a menace now, their orbit will change sooner or later so they could become a menace someday, specially those 500-1,000 asteroids with a diameter of over 1 kilometer (source: wikipedia, not 100% reliable, I know).
Lastly, let me say that I don't think an asteroid will hit us soon either, but I don't like to see statements like "nothing is hurtling toward us" from certain people or agencies. It would be more sensible to say something like "as far as we know, nothing is hurtling toward us (by now)".
Oh, and the asteroid that kill the dinosaurs had a diameter of about 15 Km (remember that asteroids are not spherical as planets) so a hill could kill us all.
Please excuse my bad English.
