It's gonna hit after all and they just don't want to tell us.

That doesn't mean I won't fap to them, c'mon

Talk about spaceflight you retarded faggots.

If it's big enough to cause a KO event, then attaching thrusters ain't gonna work.

Nor is Bruce Willis.

If you see it from far enough away (hopefully it's made of or covered with something fairly reflective, or you just get lucky), it's probably large enough that you could cover one side with white paint - and the increased reflectivity on one side would actually shift it's velocity over time.

Getting it into orbit, on the other hand, would probably be next to impossible, lest it was nearly going to do that on its own already... Though, I suppose if you had unlimited time to work with, and the starting trajectory were just right, you could just keep alternating white and black paint until you got it where you want it, maybe using the moon in the process - but it'd probably take thousands of years, by which time, you'd probably have a more practical super-tech solution.

Apophis is going to make two passes, and, while not quite large enough to create a KO event, it might be small and close enough to redirect and capture - though it'd be a monumental effort.

Granted, you don't really want to capture an asteroid with rare resources, as if you do, they aren't rare anymore, and you crash the market.
