<prompt> I-Enceladus ingenye yezinkanyezi ezinkulu zangaphakathi zeSaturn kanye neDione, iTethys, neMimas. I-Enceladus ihamba nge-238 000 km ukusuka enkabeni ye-Saturn kanye ne-180,000 km ukusuka phezulu kwamafu ayo, phakathi kwe-orbits ye-Mimas ne-Tethys. I-Enceladus ihamba nge-Saturn njalo ngamahora angama-32.9, ishesha ngokwanele ukuthi ukunyakaza kwayo kungabhekwa ngobusuku obubodwa bokubheka. I-Enceladus okwamanje isesimweni sokusebenza kwe-orbital resonance nge-Dione, igcwalisa imijikelezo emibili ezungeze i-Saturn ngomjikelezo ngamunye ogcwaliswe yi-Dione. Lokhu kuvumelana kugcina i-Enceladuss orbital eccentricity 0.0047, eyaziwa ngokuthi i-eccentricity ephoqelelwe. Lokhu okungeyona zero-eccentricity kubangela ukuguqulwa kwe-tide ye-Enceladus.  <response>: okuphoqelelwe
