The orbital evolution of Kepler-16 b, a circumbinary planet, is shown in this example using the semi-analytic model of Leung & Lee (2013), see their Fig. 5. The orbit is non-Keplerian due to the changing positions of the host stars.

Orbital evolution of circumbinary planet Kepler-16b according to VPLanet’s BINARY module. Perturbations from the central binary force orbital eccentricity and inclination oscillations for the planet (top left and right panels, respectively) and cause appreciable precession of the longitudes of the periapse and ascending node (bottom left and right panels, respectively).
