Saturnus se natuurlike satelliete
vanuit Wikipedia, die vrye ensiklopedie.
Saturnus het ses-en-vyftig bevestigde natuurlike satelliete, plus drie onbevestigde mane.
[wysig] Tabel van bevestigde mane
Die Saturniese mane word hier volgens wentelperiode gelys, van die kortste tot die langste. Mane wat so groot is dat hulle oppervlak in 'n sferoïde ingestort het word uitgelig deur 'n ligpers kleur. Titan, wat die grootte van 'n planeet het, is met 'n donkerder kleur uitgewys. Die ongewone (gevange) mane is in grys aangewys: lig grys vir satelliete wat saam met die planeet wentel en donker grys vir planete wat teen die planeet se wenteling wentel.
