Yes, just like the ancients made space be all 2 dimensional and planets move in perfectly circular orbits. It's a little funny how much Niven's influence came into Traveller, or at least these discussions: Ringworlds and Klemperer Rosettes are both dynamically unstable and both seemingly made their way from Ringworld to Traveller.

This is the case whether the center of the rosette is in free space, or itself in orbit around a star. The short-form reason is that any perturbation destroys the symmetry, which increases the perturbation, which further damages the symmetry, and so on. > > On Thu, Apr 30, 2020, 1:32 AM <xxxxxx@gmail.com> wrote: > > > > On Wed, Apr 29, 2020 at 6:16 PM Vareck Bostrom <xxxxxx@gmail.com> wrote: > > Rosettes are not dynamically stable, even when they are of the same mass. > > > I kind of thought they would be. What makes them not a stable configuration?
