Saturn
Hydrogen, helium, and a ring system of ice. The rings are metres thick and 280,000 km across.
- Distance from Sol
- 1.43 bn km
- Surface gravity
- 10.4 m/s²
- Day length
- 10.7 hrs
- Mean temperature
- −140 °C
- Orbital period
- 29.5 yrs
Atmosphere
96% hydrogen, 3% helium. Hexagonal storm locked to the north pole. Wind speeds exceed 1,800 km/h in the equatorial jet.
Notes
The rings are 99.9% water ice. Cassini Division is a 4,800 km gap kept clear by Mimas. The planet would float in a sufficiently large ocean — mean density 0.69 g/cm³.
