Calling all physicists! Am I correct in assuming that if it was the only planet in orbit about this Sun, that the orbit would be reasonably stable. However, another outer planet in the system would create gravitational drag and have the effect of retarding angular momentum so that eventually the retrograding planet would spiral towards the Sun.
Because of distance, frame-dragging should be fairly negligible on the planet.

Regard, Rob.
