    Actually, a few mm/sec is quite a lot. That could easily be more than enough to deflect an asteroid from hitting earth. That few mm/sec will accumulate over the time it takes the asteroid to travel six million miles.

      Well you would need the vector to predict that not just the speed (which they likely have, didn’t see it in the article), but pretty cool nonetheless
