    Graduate How Do Satellites Orbit Lagrange Points Without Mass?

    So, conflating the replies, may I infer that the "orbits" of bodies around Lagrange points aren't. They are not "orbits" in the true sense of the word, but the paths are better described as 'wobbles'? I return to a basic conundrum: the whole assemblage (Earth, Moon, & associated Lagrange...

    Graduate How Do Satellites Orbit Lagrange Points Without Mass?

    DrFurious: Thanks for the quick response. May I assume that you're saying "... the two bodies..." are either Earth-Moon or Earth-Sun whose configuration produces local areas of minimum potential energy? In a non-inertial frame of reference, how does the mass of the 2 bodies project a 'virtual...

    Graduate How Do Satellites Orbit Lagrange Points Without Mass?

    Physics gurus: I understood from Newton's Law that a 2 bodies would rotate around their common center of mass. Should one body disappear (Harry Potter invoked here), the other would go flying off at a tangent... like a 'David's Sling" releasing a missile. The mass of the bodies was crucial to...
