Orbit of the satellite that continues its interaction with CR-0 at z = 0. We followed the evolution of the satellite orbit to a lookback time of 6 Gyr. Top panel: Evolution of the satellite galactocentric distance from the host. Bottom panel: Evolution of the angle between the angular momentum of the disk and the satellite’s orbital angular momentum. Orbits near 180° are counterrotating, while those near 0° are corotating.
