With current rockets it isn't clear to me that we can hoist this much mass
out of the earth's gravity well.  Perhaps we could assemble a rocket in LEO
that would do it.

If you are suggesting stopping the object in its tracks, I do think not.
But you did give me an idea.  Since the object is under the gravitational
influence of the sun, then slowing the object slightly *might* cause it to
miss the earth, depending on its orbit.

Ja I think we all agree we need lots of notice ahead of time to have any
chance at all.
