Hello, Mr. Feathers The two bodies will meet in a point nearer the more massive body. It happens because the gravitational attraction is a Force, which means it produces an acceleration. The force is the same for both bodies, because of Newton's third law, action-reaction law, indeed. Newton's second law says that F = m*a , where 'F' is the force, 'm' the mass and 'a' is the acceleration. Well, for the same force, which is our situation, the 'lighter' [ie less massive] body will have a higher acceleration. It means that this body will move a bigger distance towards the 'heavier' one than the opposite. The calculus for determining exactly the meeting point is hard, so I won't include it here, because I don't know if you can handle a non-linear second order differential equation! You can find a good description of these phenomena in any good book, like, for example Mechanics (Symon). But these books ask for a good background in calculus. Hope this helps.
