Satelit Saturnus

Satelit Alam di planet Saturnus

Satelit-satelit Saturnus adalah satelit alami yang mengelilingi planet Saturnus. Satelit ini ukurannya bervariasi antara kurang dari 1 km hingga lebih besar dari planet Merkurius. Saturnus memiliki 146 satelit, Tujuh satelit cukup besar sehingga bersifat elipsoidal. Beberapa satelit terpenting Saturnus adalah Titan, satelit terbesar kedua di Tata Surya dengan atmosfer mirip Bumi yang kaya akan nitrogen dan bentang alam yang berisi danau-danau hidrokarbon dan jaringan sungai kering,[1] dan Enceladus, yang mengeluarkan gas dan debu dan mungkin memiliki air di wilayah kutub selatannya.[2]

Saturnus dan satelit-satelitnya.
Diagram ini menunjukkan orbit satelit ireguler Saturnus. Di tengah, orbit Titan, sebuah satelit yang reguler, ditandai dengan warna merah sebagai perbandingan.
