The second biggest, but for many people most beautiful planet in our Solar System, Saturn is 95 times more massive than our tiny Earth, but still just 30% of the mass of Jupiter. The rings consist of myriads of particles from the size of micrometres to a few metres and are mostly made of water, ice and rocks. Impressive as they are, the rings have an average thickness of just 20 metres. Saturn mostly consists of hydrogen, but it has a solid rocky core. As with Jupiter, don't imagine Saturn as a sphere of gas. Above the solid core there is an ocean of liquid metallic hydrogen, liquid hydrogen and liquid helium; just the outer layer is made of gas.
There are 62 moons orbiting the planet. If you could stand on one of them your view would be spectacular. Just the low temperatures would be disturbing; Saturn has a temperature of approximately -139 °C on its "surface", by which we mean its outer layer of gas.
