Fun Facts About Saturn

Fun Facts About Saturn: all 30, explained

1. Saturn is less dense than water.

   Saturn is mostly hydrogen and helium, and its average density is lower than that of water. In theory, if you had a bathtub big enough, Saturn would float, although it would not survive the experience.

2. Saturn’s rings are huge but in many places only about 10 metres thick.

   The main rings stretch hundreds of thousands of kilometres across but are extremely thin. They are made mostly of chunks of water ice, from tiny grains to pieces the size of a house.

3. Saturn has more known moons than any other planet: over 270.

   Astronomers keep finding small moons around Saturn, and its count passed 270 in 2025. The largest, Titan, is bigger than the planet Mercury and has lakes of liquid methane.

7. Saturn’s rings seem to disappear every 13 to 16 years.

   When Earth passes through the plane of the rings, we see them edge-on and they almost vanish from view. This happened in 2025.

12. Saturn’s moon Enceladus shoots water into space.

    Geysers at its south pole spray water from an ocean under the ice, and the spray feeds Saturn’s E ring.

13. There is a giant hexagon-shaped storm at Saturn’s north pole.

    Each side of the six-sided jet stream is longer than Earth is wide.

24. Saturn’s rings are slowly raining onto the planet.

    Ice particles fall into Saturn’s atmosphere, so the rings are gradually losing material.

25. Pioneer 11 was the first spacecraft to visit Saturn, in 1979.

    Voyager 1 and Voyager 2 followed in 1980 and 1981.
