    do those orbits get larger over time?

    Yes, I think they do.

    I think that expansion doesn’t increase distance, but velocity between objects (or so was my interpretation back when I looked at the formulas). That means that moving objects speed up over time. As such, orbital velocities increase, too, and that lifts their orbit - similar to when a rocket on a closed orbit propulses forward.

    But I might be wrong; I feel 70% certain about this one.
