Knowing the mass of a star, is there a maximum allowable distance of orbit?
gpt
In an isolated 2 body system (that is there is nothing else in the universe) there is no maximum distance.

In reality the answer will be the Hill sphere of the star in relation to the nearby stars. In less technical jargon, the maximum distance will be dependant on how far you can travel from the star before the gravitational influence of another star (or other object) becomes dominant.
