The best way to counter an asteroid on a collision course with Earth is not simply to hit it, but to strike it in such a spot that it will move to a safe spot. Otherwise, it could return to take a second shot at Earth.

Oops! DART got ONE thing wrong about blowing up an asteroid...and it could spell doom for Earth
