They include firing lasers into the asteroid. Crashing a spacecraft into an approaching asteroid is another possibility. As is detonating a bomb next to an incoming object. There is no risk at the moment though. NASA can't detect any asteroid currently heading towards us. No large object is likely to strike for at least several hundred years.
