Compare NASA's deep impact mission copper slug in terms of size, weight, volume, to what is publicly known of nuclear warheads currently (or perhaps
recently decomissioned) in the U.S. stockpile. I think you'll be surprised. It's too dang uncanny. (And for a certain size threshold, this may be
better than nothing. Frag with as much spread as possible and hope Earth's atmosphere gets the rest. Unfortunately if whatever's coming is too big
that still wont work.)
From the way I look at it, the entire Deep Impact "science" mission was a dry run. At least we know we can hit an inbound with enough advance warning.
It's been done and proven. But that's only part of it. The other half having the same mission with an actual big boom involved is still untested
As for other preparedness. Move assets to the geography you believe will be least affected. Other than that, choose the most hardened locations with
the best bunkers. Obviously you don't put all your eggs in one basket if that's where you think the shotgun is pointed.
In terms of what is known regarding comets/asteroids. Predictable NEO orbits are one thing, provided they're stable. The big bugaboo that you might
want to keep secret is if they're suspected of fragmenting on inbound approach to the sun. If they pull a Shoemaker-Levy as they round that corner,
those bits will fan out and because all the masses are now different it also breaks the original orbit prediction model. Sounds horrible, but if
somebody can explain where I'm wrong on that, please do.
Basically, you can only do so much. Depends on how much knowledge/resources you have.
