Within the rings lies the second largest planet in the solar system, Saturn.
Its composition is similar to that of its next-door neighbor, Jupiter, mostly hydrogen and helium gases.
The planet’s ice-covered core of iron and silica is just a little bit bigger than Earth.
Compressed hydrogen around the core resembles a metal, and is surrounded by a thick outer layer of hydrogen and helium gases.
Saturn’s density is so slight that if there were an ocean large enough to contain it, it would probably float.
While more than 700 Earths would be needed to fill up Saturn’s volume, the planet’s gravity Is lust barely more than that of Earth.
