regardless of what Nasa wants you to believe, we do not have the capability do do anything like that at this point in time.

With no air in space there would be no shockwave, even from a nuke. Any force exerted against an asteroid would have to come from the direct impact of bomb shrapnel, and that’s not likely to do much. I wonder if the radiant heat from a nuclear explosion, if directed at a specific side of an asteroid, could produce enough of an opposite force to gently nudge it onto a different path on some future close pass. It certainly wouldn’t work in the short term, but maybe it could have a longer term effect.

I always thought the tech on the salvage 1 show was on point. Nasa could learn a few things. https://youtu.be/HODkJABWo08

The Greta stare would do the job. How close do we need to get her?

I'm enough of a gentleman to try to get her back afterwards, but if the planet is in peril, that becomes secondary.
