    OK, so how would you go about applying it. It does need to be applied, correct?

    Just an impact by an object, lets say a rocket, with enough kinetic energy (not explosive power) to alter the trajectory slighty. Or, on the slower side, something equivalent to a remote contolled tugboat.

    At such vast distances with so many forces acting on objects in space, only a slight shift in trajectory is necessary.

    Might as well throw all of our garbage on that asteroid while we're at it, starting with all of the existing copies of Windows Vista.

    Agreed. But what would happen if the ball of garbage came back to earth a thousand years into the future?

    So 1000 years from now humanity would re-discover windows vista.
    Ummm... you're right, it'd be better to get hit by the asteroid.

    I see your point. Would it be very hard to control the impact, so as to get the exact redirection desired, or will just any hit from the rocket do the job? And what would the new orbit do, on it's next orbit? Would it bring the Asteroid even closer on it's next path? ---Would maybe attaching rocket engines to the asteroid, allow us to actually maneuver the asteroid in a controlled manner? and to make minor adjustments as needed. ---I'm not very good with this stuff, so was just asking.

    Not very, given a proper application of physics - the new orbit would probably have the goal of slingshotting said asteroid out of Terran orbit.

    I am also not a physicist, so I don't understand the specifics; merely the theory behind it.

    Your doing a fine job. at least you have a plan. but as with the 2029 comet, or asteroid, it will pass us by this trip, but the next one won't be so nice. ---My memory is not so great. I hope I have those dates right. I forget it's next arrival.---I must research. I'll get back to ya, when I have something. Be well.
