> astroid large enough to cause the surface to liquify (into molton rock) Well, asteroid collisions follow a power law; the bigger the collision, the less often they happen. They get rarer the older the solar system gets, as they are consumed (AFAWCT). But asteroids aren't self-replicating and they don't tell themselves how moral it is to eat everything in sight for the sake of some three letter acronym called GDP.
