Saturn Fun Facts

Illustration of Saturn, Cassini and Huygens in space
Saturn is sometimes called "The Jewel of the Solar System." It is a fascinating planet that is nothing like our own. Humans have been gazing up at Saturn and wondering about it for thousands of years.

Here are some fun facts about the Ringed Planet.

Illustration shows that nine Earths would fit across Saturn
Round Orange Bullet Saturn is huge. It is the second largest planet in our Solar System. Only Jupiter is bigger. If you could line them up, more than nine Earths would fit across Saturn.

Round Orange Bullet Unlike Earth, Saturn is made mostly of hydrogen and helium. While it has heavier materials in the core, Saturn has no surface on which you could stand.

Round Orange Bullet Its beautiful rings are not solid either. They are made up of particles of ice, dust and rock.

Round Orange Bullet Some of these particles are as tiny as grains of sand, some are much larger than skyscrapers. Actually, some are up to a kilometer (more than half-a-mile) across.

Round Orange Bullet The rings are huge yet tiny: the main rings could cover almost the entire distance between Earth and the moon yet they are less than a kilometer (about half-a-mile) thick.

Round Orange Bullet We now know that other planets have rings, but Saturn's are the only ones that are visible from Earth even with a small telescope.

Round Orange Bullet Because Saturn is tilted, when its rings are facing Earth edge on they "disappear" from our view. We now know this happens every 14 years or so, but poor Galileo questioned his sanity when they "disappeared" and then "reappeared" on him a few years later.

Round Orange Bullet It's pretty windy on Saturn. Winds around the planet's equator can reach 1,800 kilometers (1,118 miles) per hour. In comparison, the fastest winds on Earth "only" reach about 400 kilometers ( about 250 miles) per hour.

Round Orange Bullet Saturn goes around the Sun very slowly, but spins on its axis extremely fast. A Saturn year lasts for more than 29 Earth years, but a Saturn day only lasts 10 hours and 14 minutes.

Round Orange Bullet Because of this rapid spin and its low-density interior, Saturn is noticeably flattened, top and bottom. Saturn is 10 percent fatter in the middle than at the poles.

Round Orange Bullet Saturn is the only planet in our Solar System that is less dense than water. Which means that if you could build a ridiculously large bathtub, Saturn would actually float in it.

Round Orange Bullet Its density is only 0.13 that of Earth. (That's because Earth is made of rocks and stuff, and Saturn is pretty much just gas.)

Illustration of Roman god of agriculture
Round Orange Bullet The Ringed Planet is so far away from the Sun that it receives only about 1/80th the amount of sunlight that we do here on Earth. Yes, the Sun appears much smaller from there.

Round Orange Bullet The planet is named after Saturn, the Roman god of agriculture. The day Saturday is also named after him.
