Also I would have to think that the junction itself actually orbits Mc-A (nothing in space is "absolutely fixed").
According to HOS, The two stars orbit between 650 and 827 light-minutes apart. A couple pages later it then says "The wormhole nexus lies 412 light-minutes from Manticore A." The way they said it could mean that it is always that distance, or it could mean that it is currently at that distance, so nothing there. However, given the above numbers, one could extrapolate that it would almost have to be in an orbit around the center of mass of the system, rather than around one star.
On the other hand, the fact that hyper bridges are not normal space phenomenon, but rather Hyperspace that has impinged on normal space, it is totally possible in my mind that the interact with gravity in an entirely different way. Until you can show me the math of the Honorverse or Word Of RFC, we don't actually know that they can't be absolutely fixed.
