30 Interesting Facts About Saturn, Updated for 2026

Here are the most interesting facts about Saturn in short: it is the second largest planet, it is less dense than water, its day lasts about 10.5 hours, its rings are mostly ice and very thin, and it has 293 confirmed moons, more than any other planet. Its moon Titan is bigger than Mercury.

Saturn is the planet most people picture when they think of space. We have updated this list for 2026, including the new moon count, which has more than quadrupled since this article was first written, when the figure was 64.

30 interesting facts about Saturn

We have grouped the facts so you can jump to the part you care about most.

Size, structure and weather

1. Saturn is the sixth planet from the Sun

It orbits at an average of about 9.6 times Earth’s distance from the Sun, roughly 1.43 billion km.

2. It is the second largest planet

Only Jupiter is bigger. Saturn is about 120,500 km wide at the equator, around nine times the width of Earth.

3. It is about 95 times heavier than Earth

For all its size, Saturn is not as massive as you might expect, because it is made mostly of light gases.

4. It would float in water

Saturn’s average density is about 0.69 grams per cubic centimetre, lower than water. It is the only planet in the solar system less dense than water.

5. It is a gas giant made of hydrogen and helium

Like Jupiter, Saturn has no solid surface to stand on. Pressure and heat rise steadily as you go deeper.

6. It is the most flattened planet

Saturn spins so fast that it bulges at the middle. Its width at the equator is more than 10 percent greater than its height from pole to pole.

7. A day on Saturn lasts about 10.5 hours

Scientists estimate one rotation at about 10 hours 33 minutes. The exact figure was hard to pin down because the planet has no fixed surface.

8. A year on Saturn lasts about 29.5 Earth years

If you were born on Saturn, you would celebrate your first birthday at the age of 29 in Earth years.

9. Its winds are among the fastest in the solar system

Winds can reach about 1,800 km/h. Only Neptune has faster winds.

10. It is extremely cold

Typical cloud-top temperatures are around minus 185 degrees Celsius.

11. There is a giant hexagon at its north pole

A six-sided wave pattern circles Saturn’s north pole. Each side is about 14,500 km long, longer than Earth is wide.

Saturn’s rings

12. Its rings are huge but very thin

The main rings stretch more than 1 lakh km out from the planet but are, on average, only about 20 metres thick.

13. The rings are mostly water ice

Ring particles range from tiny grains to chunks as big as houses, made mostly of ice with some rock.

14. Scientists still argue about how old the rings are

Some think they formed with Saturn about 4.5 billion years ago. Others think they are only around 100 million years old, possibly the remains of a destroyed moon.

15. The rings seem to vanish every few years

Twice in each Saturn year, Earth lines up with the ring plane and the rings look like a thin line or disappear in small telescopes. The most recent crossing was in 2025.

16. Galileo was the first to see Saturn through a telescope

In 1610 he saw odd shapes on either side of the planet and thought they might be moons. They were the rings.

17. Christiaan Huygens solved the ring puzzle

In 1655 Huygens described the rings correctly. The same year he discovered Titan, Saturn’s largest moon.

Saturn’s moons

18. Saturn has 293 confirmed moons

As of June 2026, astronomers had confirmed 293 moons, by far the most of any planet. Only 63 of them have formal names so far.

19. 128 moons were announced in one go

In March 2025, astronomers announced 128 new moons at once, taking the total to 274. More batches followed in 2026.

20. It overtook Jupiter for the most moons

Saturn passed Jupiter’s moon count in 2019 and has stayed ahead since.

21. Titan is bigger than the planet Mercury

Titan is the second largest moon in the solar system after Jupiter’s Ganymede. It is wider than Mercury but less massive.

22. Titan has lakes, but not of water

Titan is the only moon with a thick atmosphere. Its lakes and seas are filled with liquid methane and ethane.

23. A probe landed on Titan in 2005

The European Huygens probe, carried by Cassini, landed on Titan in January 2005. It is still the farthest landing ever made by a spacecraft.

24. Enceladus sprays water into space

Cassini found more than 100 geysers at the south pole of the small moon Enceladus, fed by a hidden ocean of liquid water below the ice.

Missions and sky watching

25. Pioneer 11 was the first spacecraft to visit

NASA’s Pioneer 11 flew past Saturn in September 1979.

26. Both Voyagers followed

Voyager 1 passed Saturn in November 1980 and Voyager 2 in August 1981, sending back the first detailed images of the rings.

27. Cassini studied Saturn for 13 years

Cassini entered orbit on 1 July 2004. On 15 September 2017 it dived into Saturn’s atmosphere on purpose, so it could not contaminate moons that might support life.

28. A drone is going to Titan

NASA’s Dragonfly, a nuclear-powered rotorcraft, is scheduled to launch in July 2028 and reach Titan in 2034.

29. You can see Saturn without a telescope

Saturn is one of five planets visible to the naked eye. It looks like a bright, steady, yellowish star.

30. Saturday is named after it

The planet is named after Saturn, the Roman god of farming and wealth. Saturday takes its name from the same god.

Saturn in films and pop culture

Saturn’s rings make it a favourite for science fiction. In Christopher Nolan’s Interstellar (2014), the crew travels to a wormhole near Saturn. For more sci-fi recommendations, see our Hollywood section and browse our listicles.
