if there is perpetual motion, then how, other than entering another planets gravity field, can a meteor change direction?
Only by being deflected by Bruce Willis, no, seriously, by colliding with another heavenly object, it has happened.

How would a bunker buster not work on space? It's basically a warhead that penetrates like what ever you put infront of it. The BLU-113 (I think that was the name) is rated 6+ meters of reinforced concrete. (video here
http://www.liveleak.com/view?i=602065a869) Not sure if that's the BLU-133, but it's definitely a bunker buster warhead. Don't know how gravity would affect it's work, on earth all it gains from gravity is the speed, which would be easy to do with a rocket engine in space. And a nuclear explosion inside the asteroid would definitely cause a lot of damage to it. Ever seen the underground or underwater nuclear tests? Lots of mass on top of the bomb, but still a pretty decent boom. Now those are normal nukes, shove 50 of them into 1 missile and the boom will be a little bigger.
Sorry, but I still maintain it'll be as I have said, it will act the same as a powerful rocket engine, for every action there's got to be a reaction, the mass of an asteroid is mostly iron, immensely strong, so, even if they manage to bore a hole, the explosion even if it was nuclear, would only push in one direction, out of the borehole, an uncontained explosiion like a large firework rocket, & give an almighty shove to the asteroid, admittedly it wouldn't move much, given the size of it, but with no gravity, therefore no friction it would keep on going, yes, it would be great if it pushes it away from Earth, but that can't be guaranteed, as the explosion might have a side effect, & alter it's course towards Earth.
Can anyone else see that?, I've worked it out pretty logically I think.
