The problem with JohnWDailey's proposed system is that the central mass, a pair of F5V stars, close to the limit of stars which could last long enough to have habitable planets, would not be massive enough to have so many other pairs of stars in orbit in a ring around them. The two F5 stars would total only 2.60 times the mass of the Sun, while the 6 outer pairs would total 10.68 times the mass of the Sun, more than 4 times the mass of the central pair. The system would be fine with one of the pairs of smaller stars orbiting the central pair. | |

Golding | Actually it has been claimed that a system of 7 to 42 equally massed and equally space objects can orbit a much more massive central body and be stable. planetplanet.net/2017/05/03/… - ui.adsabs.harvard.edu/abs/2010CeMDA.107..487S/abstract A Klemperer rosette does not have a central body.

| Sep 13, 2021 at 2:23 | comment | added | Mike Serfas | This system is fairly similar to the Klemperer rosette proposed in Ringworld by Larry Niven. Unfortunately, Niven was not an expert on stability of Ringwords or other planetary systems. :) As explained at that article, the rosettes are not actually stable. Making each moving component a binary star probably doesn't help to avoid perturbation of the system. | |
