A imagined disaster worth some speculation

In a discussion of how many ice cubes it would take to put out the sun (hint: that trick never works), a much more interesting scenario emerged.
It’s also possible that collision with enough non-fusible material, such as a mass of nickel-iron asteroids, could dissipate the nuclear fire, and almost certainly lead to formation of a black hole, a cool concept all by itself.

I've never seen this addressed in science fiction, but it seems like a worthy topic for hard science fiction, and possibly also for make-it-up-as-you-go science fiction.

Supposing you were limited to the laws of physics as they are now known, what could be done? How much warning would you get about the flock of asteroids? Is there anything conceivable which could be done to divert them? Or move the Earth out fast enough, and then keep it warm? I'm assuming that moving the sun is out of the question.

Of course, it's conceivable that the asteroids are an alien attack, in which case there's a whole nother bunch of questions and difficulties.
