for ease of explanation, imagine that the barycenter of two planets is the center of a wheel and that the planets revolve around the edges of the tire. the center of the tire (barycenter) is in orbit around sun, as if the wheel is rolling around in its orbit. my question is, is this possible? of course every time one planet would swing closer to the sun it would be pulled farther out of orbit, but would another large planetary object (perhaps in an outer ring) counter-balance the sun`s gravity? what possible positioning of these planets might help them maintain their orbit`s integrity? thanks
