This form will calculate energy requirements for various methods of destroying asteroids. Please note that with very large asteroids, gravity can become significant, thus reducing the usefulness of this data. For an Earth-sized planetary body, gravitational binding energy handily exceeds both fragmentation and vapourization energy.
