sentences:  Actaea is magnitudes fainter than Salacia, implying a diameter ratio of 2.98 for equal albedos.Hence, assuming equal albedos, it has a diameter of Actaea has the same color as Salacia (V−I = and , respectively), supporting the assumption of equal albedos.It has been calculated that the Salacia system should have undergone enough tidal evolution to circularize their orbits, which is consistent with the low measured eccentricity, but that the primary need not have been tidally locked.
