Paintballs may deflect an incoming asteroid

In the event that a giant asteroid is headed toward Earth, youd better hope that its blindingly white. A pale asteroid would reflect sunlight and over time, this bouncing of photons off its surface could create enough of a force to push the asteroid off its course.

How might one encourage such a deflection? The answer, according to an MIT graduate student: with a volley or two of space-launched paintballs.
