If you like. But I was trying to clarify that LaGrange points are a solution to a three body gravatational system in which we assume that larger bodies in the system experience no gravitational pull any body smaller than themselves. There are no exact solutions to the general case of three (or more) body gravitational systems. Only special case simplifications.

Isn’t that the premise of Gor? Just asking, 'cos I’ve never read any of that series. :dubious:
