What is the most populated/numerous stellar system in which the orbits of all objects are known? I posed a question or two on here a couple months or so ago about the orbital patterns of each of the seven stars in the two septenary star systems Nu Scorpii and AR Cassiopeiae. They remain unanswered so I have to assume the answer is unknown. So, now I want to what the most numerous star system is for which we actually do know the orbital pattern, and obviously I want to know the orbital pattern.  

I am NOT talking about a star with multiple planetary or other smaller bodies. I am talking about multiple STAR systems. Do we know the orbit for systems of multiple stars. Again, I'm not talking about every rock larger than a school bus. I mean STARS. Stars that have nuclear fusion occurring.

The answer is none. Other than our own solar system, astronomers don't know if they know all of the large bodies (aka planets) orbiting any given star system. Presumably other star systems have asteroids, comets, and other stuff. The orbits of those small bodies in star systems is unknown, and will remain unknowable for a long time.

We don't even know that for our own solar system. If we did, we wouldn't have to worry about killer asteroids and comets.
