If we find the asteroid early enough, I’m in favor of a small orbiter designed to cover the surface of the asteroid in titanium dioxide. Not only would the asteroid become much more visible and easier to track, but it should also sustain greater solar pressure outward, which should continually nudge the asteroid into a wider orbit without resorting to active propulsion units subject to failure. Just a thought.

What’s needed is an ion propulsion craft with two opposing engines that can hover near an oncoming asteroid and hold its position while nudging it away. A craft so heavy it needs only one engine (because gravity would push equally toward it) would surely be too expensive to put in place.

I’m not worried. I remember what I was taught in school. Duck and Cover.
If it’s good enough for an A-Bomb, it.s good enough for an asteroid.
