We're just going to let it fly by? Harpoon it!
A nuke, in atmosphere, generates a pressure wave due to turning air into plasma. In space, a nuke would functionally just be a high temperature spherical particle cloud.
Firing a nuke at an asteroid would do almost nothing. The momentum, and shear velocity, are significantly greater than even the largest nuclear device could challenge. On the other hand, a series of nuclear devices exploding in a reinforced hemisphere could create a force that would redirect an asteroid's trajectory.
The solar sail is the safer, lower impact version of this idea.
Yeah, a huge asteroid could hit us tomorrow without any indication from scientists. We find crap in the sky all the time, that we never saw before. Only a small fragment of the night sky is charted, and even then a nearly black body traveling directly at us might not be visible on the visible spectrum.
Believe what you want, but mother nature is a kind soul compared to the universe. Nature tends to kill slowly, but space can snuff out all life in one crappy collision.
well one thing is for sure, nobody at NASA is going to consult us!
You are right if you include wartime nukes, lest you forget Tsar Bomba and other post-war test nukes. Tsar Bomba would be about double that of said asteroid's explosive power. It would definitely get the asteroids attention, now we just need to be able to shoot the nuke out instead of dropping it...
