Theoretically, that doesn't simplify the problem at all. Practically, we can say that Mass_probe=0, in which case we have a 2-body problem. We need to do that even if we do find a closed form solution to the n-body problem (which might be provably impossible), becuase in reality there is an infinite number of bodys in the system.
