For this study, the team wanted to find out how many worlds could be packed into a similar orbit. They started with the assumption that all worlds would be Earth-mass, and they would orbit a sun-like star at 1 au. They found that as you add more planets the orbits become a bit more variable, but it is possible to pack as many as 24 Earth worlds into stable horseshoe resonances. The orbits of these worlds would be stable for billions of years with the right set-up. Planetary systems that could last forever
I never dreamt this was possible and it neither did science fiction as far as I know.
