Denderedzwa: Denderedzwa rakapfava reguruva riripo rakakomberedza nharaunda inotenderedzwa neEpimetheus naJanus, sezvakaratidzwa nemifananidzo yakatorwa muchiedza chakapararira kumberi neCassini spacecraft muna 2006. Denderedzwa rine radial chiyero chemakiromita anenge 5000. Kunobva kwayo zvikamu zvinoputika kubva kumusoro kwavo nekukanganiswa nemeteoroid, izvo zvino zvinoumba denderedzwa rakapararira kutenderedza nzira dzadzo dzekutenderera. Pamwe naJanus, Epimetheus anoita semufudzi wemwedzi, achichengetedza muganho wekunze weA Ring mune 7:6 orbital resonance. Mhedzisiro yacho inonyanya kuoneka kana Janus ane hombe ari pane resonant (yemukati) orbit. Mubvunzo: Ndeipi spacecraft yakatora mifananidzo yaJanus?
