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.
