    Ohh, lucky. We better remember to check our asteroid privilege in the event we meet any aliens who have been asteroid disadvantaged.....

    Do you think that if it was going to hit us, we would have been properly informed and risk global panic?

    Much better to under fund detection systems and say 'Opps - Sorry' afterwards!

    There is a lot of sky and only a few telescopes. We're relying on objects being brighter than the space surrounding them.

    We dont really have any other forms of detection. A space based radar system would be astronomical in cost and wouldn't provide much range in on a stellar scale. LIDAR would be slightly better but range has an inverse relationship to radius. The more area we need to scan, the less reliable long distance bounceback becomes. The fact is, we simply dont have the technology to establish a detection grid... let alone the technology to stop an asteroid capable of causing significant damage (despite what the movies say, nukes and Bruce Willis are not good enough to deflect or destroy an asteroid).

    Yep, it really is blind luck we haven't been hit by an asteroid. But dont despair, the Yellowstone caldera is only 20,000 odd years overdue for an explosion.
