Lighter than water. Saturn has no surface either; this is its cloud bands. It is lighter than water, and its rings, mostly ice, would reach most of the way from the Earth to the Moon.

What you’re seeing
Saturn’s cloud bands, drawn from spacecraft pictures. There is no ground beneath them, and its rings aren’t on a map of the planet.
Named places
The hexagon: A six-sided jet stream around the north pole, about 29,000 km across: each side is longer than the Earth is wide.
South polar storm: A storm about 8,000 km across sits on the south pole, with a clear eye walled by towering cloud, like a hurricane’s.
Great White Spot: Every Saturn year or so, about 30 of ours, a giant storm breaks out. The last, in 2010, began here and stretched until it wrapped the whole planet.
Equatorial jet: Winds along the equator blow at up to 1,800 km/h, among the fastest in the solar system.
