Satelit Saturnus

Satelit Alam di planet Saturnus Dari Wikipedia, ensiklopedia bebas

Satelit 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 Enseladus, yang mengeluarkan gas dan debu dan mungkin memiliki air di wilayah kutub selatannya.[2]

Catatan kaki

  1. Diameter dan dimensi dari satelit bagian dalam: Pan, Janus, Methone, Pallene, Telepso, Calypso, Helene, Hyperion dan Phoebe diambil dari Thomas 2010, Tabel 3.[3] Diameter dan dimensi Mimas, Enseladus, Tetis, Dione, Rea, dan Iapetus diambil dari Thomas 2010, Tabel 1.[3] Perkiraan ukuran satelit Saturnus lainnya berasal dari situs web Scott Sheppard.[6]
  2. Massa dari bulan-bulan besar diambil dari Jacobson, 2006.[4] Massa Pan, Daphnis, Atlas, Prometheus, Pandora, Epimetheus, Janus, Hyperion dan Phoebe diambil dari Thomas, 2010, Tabel 3.[3] Massa bulan-bulan kecil lainnya dihitung dengan asumsi massa jenis 1.3 g/cm3.
  3. Parameter orbit diambil dari Spitale, et al. 2006,[7] IAU-MPC Natural Satellites Ephemeris Service,[8] dan NASA/NSSDC.[5]
  4. Periode orbit negatif menunjukkan orbit retrograde di sekitar Saturnus (berlawanan dengan rotasi planet).
  5. Ke ekuator Saturnus untuk satelit reguler, dan ke ekliptika untuk satelit ireguler.
