A number of other strategies have been proposed that could eventually be developed into working deflection missions for asteroids heading toward Earth. one proposal is to focus solar energy at the surface of the asteroid, vaporizing material from the surface, eventually deflecting it from its collision course. It may be possible to wrap incoming asteroids with reflective sheeting or to add reflective dust to the surface, so that part of the asteroid receives additional radiation from the sun, and radiation pressure distributed unequally on the asteroid may be enough to deflect it from its orbit. Another idea is to attach to the asteroid a large solar sail, which would absorb solar energy and change its orbit.
