Sorry - Yes Kemplerer Rosettes
I can of course make Plans for the future in my Game - I am the Gamemaster, I write all of the Scpout / Discovery Reports - Stars, Planets, etc.
Of course Kemplerer Rosettes are unstable in the long run - but any Species / Race / Peoples which can "engineer" Planets and Star Systems, Move Planets and Stars - can "correct" any significiant perturbations from time to time.
Our Confederation ( partly Humans ) has Gravity Control - which amounts to Tractor and Pressor Beams, and loads of Power from cheap, clean Fusion Power. But the "Cat People" of the Tigre Sector are some 250,000 years ahead of us - in theory. Early Humans / Hominids evolved some 500,000 years ago on Earth - the "Cat People" evolved as an Intelligent Species some 750,000 years ago.
Re: Satellites - the "Cat" Peoples of The Tigre Sector cleared out all non-useful Planets, in building their Systems - their are only earth-like Worlds and their necessary Moons.
