    Yowsers! So, it's as big as the Statue of Liberty? It would be ironic if it actually hit the Statue of Liberty and took out most of Manhattan. Grab the movie rights now and you're onto a winner!

    Just 1/1.000.000 chance of hitting us. Pretty long odds.

    Look at the number above;

    It was a million to one that I would just write that particular one down (between 1 and 1,000,000) and yet I did it.

    Those odds and longer come up week in week out in various circumstances.

    There was one before Easter wasn't there? Are they queueing up out there to take pot shots at us? :(

    Hmmmm, what if it is the actual statue of liberty - coming at us in some strange time warp? :confused::o

    There is a near miss asteroid every few weeks. By near miss they often mean further away than the moon! Yet the day something came in on Russia on 15th February 2013 nobody saw it coming until it arrived. If that had been over London it would have caused carnage from the shockwave alone.

    I thought that was compulsory for asteroids and comets. Maybe the damn thing is attracting them!

    Could be maybe it was that what blew it and the world up. Then the apes evolved rather than nuclear war. Taylor was cursing the wrong people they were not maniacs at all. :D

    Hopefully it'll do us all a favour and hit the middle east.

    I hope not. There'll be innocent people over there, as well as the IS morons.

    Phew!

    I was afraid it was going to be 358,271!

    Or even worse:
    7,189,873,285,236,875,486,157,147,842,549,563,935,965,984,128,431,425,926,183,583,189,765,183,138,534,730,093,263

    Odds of a million to one against might well come in week in week out if there are millions of events that might potentially happen - but they fail to come up much more often.

    How much is that in double-decker units? We're British, dammit!

    Bruce Willis and Robert Duvall will save us.

    Sadly that’s not a realistic option;

    They both died during a previous ill-fated attempt to divert an asteroid. :(

    But they died so we could live!

    Million-to-one odds turn up nine times out of ten*, this is a well-documented fact.





    * Corporal Nobbs? I can't remember who said it but there was definitely someone standing on one leg wearing a blindfold and about to shoot an arrow and I suspect even the gargoyles had taken cover

    I think the million to one comment was not arrived at scientifically.

    the more telescopes there are, the more asteroids will be spotted.....

    Given the asteroid is traversing space at newtonian speeds (not einsteinian speeds), it must be quite easy to calculate its course based on its cuurent trajectory, relative well know position of nearby planets which could influence the trajectory.

    There will be an uncertainty band on the calculations, but provided the estimated closet approach is so big enough, such that even allowing for calculational uncertainty, it will miss the Earth, then statements such as a 1 in 1 million chance have no meaning and are just typical press type statements.

    So either the asteroid will pass so far away there is no chance, or it is passing so close that there is a realistic chance of colliding which can be reasonably well calculated.

    On the grounds we are are not hearing anything to the contrary, I assume there is no chance. (Of course, conspiracy theorists might say we are not being told the truth).

    I bet America comes up with "lets blow that up". That's their answer to everything "lets kill it".

    Do you mean the asteroid, or the large blank area in your post #15 ? :confused:

    The problem would be the confidence with which its position and trajectory are known. It will be fairly well known in what direction the object is, and how quickly that direction is changing, but there'll be a certain amount of guesswork at first exactly how far away the object is. Roughly how far away can be estimated, and the closer the object is the greater the accuracy with which that distance can be fixed. Calculations based on an initial estimate will most likely produce a range of values for the closest approach to Earth. If that range is, say, 1,000,000 - 2,000,000 miles, then all is well. If it's 500,000 miles on one side to 500,000 miles on the other side, then there is a chance of being hit. Given that on that kind of scale, the Earth is still a fairly small target (even allowing for the fact that we're at the bottom of a gravity well), then it's not a very big chance,

    I suppose that you could do some statistical calculations and come up with a number for the probability that the combination of position and trajectory is one that will lead to impact with the Earth, but I'd agree with you that statements like "one in a million" are shorthand for "very, very unlikely"

    Long odds? If it's a 1/1.000 (i.e. 1/1) it's an absolute certainty!

    Surprised this hasn't been covered in the papers...
