Asteroid impact could be stopped with nuclear missiles, study suggests - The Jerusalem Post

Many scientists feared using asteroid disruption - destroying it, like with nuclear weapons - could cause the fragments to cause more damage, but a new study suggests otherwise.

The simulation in question used the model of a one-megaton nuclear bomb detonating on the surface of an asteroid measuring 100 meters long and accounted for several possible different orbits, the sun, and the gravity by other large objects in space. It was also assumed that the asteroid was hit with the bomb several months ahead of its planned impact against the planet.
