      • 1885, Astronomical, Magnetic and Meteorological Observations Made at the United States Naval Observatory, It is difficult by means of the old observations to separate the annual motion of the perisaturnium very accurately from any small error that may still exist in the mean motion of the satellite, but on the whole it appears that the elements are now determined with a good degree of approximation.
      • 1974, YÅ«suke Hagihara, Celestial mechanics - Volume 3 , G. Struve (1924) drew attention to the motion of the perisaturnium of Rhea by noting the fact that, although there is no commensuability relation between the mean motions of Rhea and of any other Saturnian satellite, the perisaturnium of Rhea performs a libration in longitude about the perisaturnium of Titan.
      • 2013, B.A. Steves & ‎Archie E. Roy, The Dynamics of Small Bodies in the Solar System, If they were exactly following such a periodic solution, then, at a conjunction of the two satellites, that is, when φ = 0, we would have l1= 0, that is, Enceladus, which is on the inner of the two orbits, would be at perisaturnium, and alsol2= Ï€, so that Dione, which is on the outer of the two orbits, would be at aposaturnium.
