Abstract: Asteroids must have been hitting each other throughout the age of the Solar System. What has it done to them? To make analytical calculations of what happens when one asteroid hits another, one is forced into the unrealistic assumption that the bodies are spherical and rigid. But now a numerical model shows what happens when irregular, inhomogeneous asteroids suffer high-velocity impacts. The 'rubble-pile' asteroids that result would be relatively difficult to deflect from a collision course to Earth.
