well i think you would have to look at the planets/roids orbit leight. Sometimes it is set very long. yesterday one planet was "orbiting" thru half of my screen hitting nearby solar system lol
This is partially intentional.
I say partially because the orbits are not quite as tight as I would like, but it seems a good balance in general, plus it's kind of cool watching planetoids change parent stars.
this will not likely be an ongoing problem though, as I also intend on expanding the scrollable layout area, but keeping the same amount of stars (IE more free area per star system).
I fixed the persistence problem.
