Can anyone give a serious response. What if the asteroid today was actually headed towards us. What would the solution be to deflect it?
Man are ya seriously asking these people to know anything about much?
They've absolutely no idea what you're talking about. Perhaps you should go find some data; which is readily available; wherein you can point to the studies which speak to the use of Nuclear warheads as a means to push Near-earth orbiting bodies off of a colliding trajectory.
Ya have to understand that these people are, for the most part, idiots.
One doesn't come to believe that the best solution where the question is one of right and wrong; is to compromise with wrong... and have much to say about... much. (That's how they grew to be Progressives... they stopped growing, intellectually speaking.)
Says the party where Palin and Bachmann are considered rockstars.

Most asteroids are made of loosely packed material. The larger asteroids are between 7 and 13 miles across. Exploding a nuclear bomb on one or in one wouldn't disintegrate it, rather, it would "ripple", similar to hitting a pool of water with a baseball bat.
About the only way to stop such an asteroid would be to very slightly "divert" it's course so far away from earth that by time it got here, it would pass by harmlessly.
Considering that the world spends only a few million a year on watching "space", stopping such an asteroid is very unlikely because we probably wouldn't be able to see it until much too late.
This is taught in even the most basic science classes.
PLANETARY DEFENSE CONFERENCE PART 2: MITIGATION PROPOSALS
"Harris emphasized that asteroid mitigation is not a job for leftover ICBMs and warheads, that experimental nuclear explosions in space are politically difficult, and of course the cost of risk prevention should not exceed its value.
Several speakers discussed the use of nuclear explosives either for destruction or deflection. David Dearborn (Livermore National Lab) discussed coupling of nuclear blast energy into NEOs. Nuclear explosives provide by far the most efficient packaging of energy (a million times more energy than the same mass of chemical explosive). For deflection, he noted that only by applying the force vector along the trajectory do we change the total angular momentum of the NEA and provide a shift that is cumulative over many orbits. Forces applied in other directions to change inclination or eccentricity do not produce cumulative effects (except in unusual resonant return cases).
With conservation of momentum, we can readily calculate how much reaction mass must be ejected based on mass of asteroid, velocity of material ejected, and required change in asteroid velocity. For deflection, must keep delta v much less than escape velocity. Standoff explosion heats rock and vaporizes material to exert reaction force. The explosion needs to be within 1 radius or we lose most of energy. For a delta-v of 1 cm/sec on kilometer-scale object, we need to vaporize the top 2 cm. X-rays dont penetrate deep enough, but neutrons are more penetrating and give centimeters of heating. We could deflect a 1 km object by cm/s with a few megatons explosion of a neutron-rich nuclear device. "
ROFL
I'm now convinced US Army Retired is a liberal sock puppet intent on making conservatives look stupid.
fools
obama will fart and blow the asteroid off course!
We will just put a bunch of high school students into space ships that have particle beam cannons. The ones that score highest against the asteroid will be given an evening with any two Playmates of the Month of their choice. Plus a lifetime supply of Jolt Cola or Mt. Dew

Posting for all the public to see---your fascination with the habits and lifestyle of high school children---it's just too creepy for words.
I want to ride a rocket while listening to Aerosmith, screw Bruce Willis and Affleck!You have got to be fucking kidding me. Killer fucking asteroids? DO you really think that scenarion where Bruce Willis and Ben Affleck strap themselves to an ACME rocket while jamming to Aerosmith is actually fucking viable? You have got to be fucking kidding me.
