Avoid Killer Asteroids: Simple Solution Discovered

An asteroid has a lot of mass and probably a lot of velocity. If you know a rocket that can get to said asteroid, and still have the delta velocity available to push an asteroid out of orbit, give NASA a ring!

Perhaps you've heard about the project channel Discovery "Day of the asteroid." They are asked to send methods of protection from asteroids, but I decided to write to you. It's strange, but nobody even discusses this method deviations, even very large stones. Blowing them with nuclear weapons may not be effective or even harmful. But a series of nuclear explosions near the trajectory of the asteroid at a distance of action of blast waves, on the side opposite to the desired direction of change in its trajectory, can really solve the problem. Nuclear weapons we have a lot on Earth. Certainly it needs to check the trajectory of the asteroid, after each explosion to adjust the position of the next explosion.
Questions. Where is he now? Can we reach it? What is the accuracy of hitting a given point? How fast can we find out if he strayed and how much?
