Of course, such a walk would be a challenge, since Saturn's composition is almost completely hydrogen and helium, and lacks a solid surface. Twitch: https://twitch.tv/fcain The Guide to Space is a series of space and astronomy poddcasts by Fraser Cain, publisher of Universe Today, Episode 700: Interview: Wallace Arthur and the Biological Universe. Although the planet is only a third the mass of Jupiter, it is about 80 percent as large, contributing to its low density. Uranus is about four times bigger than Earth. The equatorial diameter of Saturn is 120,536 km ± 8 km (74,898 ± 5 mi) – or the equivalent of almost 9.5 Earths. Every millimeter in this scale model solar system represents 10 billion millimeters in the real solar system! This work is licensed under a Creative Commons Attribution 4.0 International License. It also has 29 unconfirmed moons we need to learn more about. Learn More About Saturn. Saturn is visibly flattened at the poles, a result of the very fast rotation of the planet on its axis. Despite its size, its mass exceeds all the moons smaller than itself combined. The polar diameter of Saturn is 108,728 km, meaning that it is flattened by a factor of 9.796%. Saturn has a thick atmosphere. In 2007, it was determined that the varying radio emissions from the planet did not match Saturn’s rotation rate. System II encompasses all other areas of Saturn and has a rotational speed of 10 hours 38 minutes and 25.4 seconds. Space calendar 2020: Rocket launches, sky events, missions & more! The five rings are composed primarily of chunks of water-ice, mixed with pieces of rocks. The second stage was also discarded. A walk around the equator of Saturn would carry you 227,349 miles (365,882 kilometers). What Is The Angular Diameter Of Saturn (in Arc Seconds) As Seen From Earth When The Two Planets Are Farthest Apart? One year on Saturn is the same as 29 Earth years. Saturn, like all of the other planets, is an oblate spheriod. To make things even more difficult, the visible features of the planet’s atmosphere rotate at different speeds depending on their latitude. Although several other planets boast rings, Saturn's are the largest and most visually stunning. Please refresh the page and try again. The mass of Saturn is 95 times the mass of Earth. Follow us on Twitter: @universetoday Saturn is about 9.5 times farther away from the Sun than Earth. Despite these numbers, the rotational speed of the planet’s interior is currently impossible to measure precisely. However, Saturn's gravity is only 1.08 times the gravity on Earth because Saturn is such a large planet. Carry you 227,349 miles ( 58,232 kilometers ) life in the Solar system ads on this site see.
