Ring-a-Round the Saturn - NASA

Saturn is a funny-looking planet. True, it's not the only planet with rings. Jupiter, Uranus and Neptune have rings, too. But Saturn's rings are the biggest and brightest.

Universe Today - Orbit of Saturn

The orbit of Saturn lasts 29.7 years. In other words, during the time Saturn completes one full revolution around the Sun, Earth has gone through almost 30 years.

Saturn Astronomy - Encyclopedia

Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years.

See Ringed Planet Saturn at its Best - Astronomy Now

The one planet guaranteed to elicit an exclamation of wonder when first seen through a telescope is Saturn, particularly now that its glorious ring system is so prominently displayed. And it doesn't require a large telescope either - A good quality 60mm refractor is more than adequate to distinguish Saturn's globe and encompassing rings.

Saturn - Views of the Solar System

Saturn is the sixth planet from the Sun and is the second largest in the solar system with an equatorial diameter of 119,300 km. Saturn is visibly flattened at the poles, a result of the very fast rotation of the planet on its axis.

Adorned with thousands of beautiful ringlets, Saturn is unique among the planets. All four gas giant planets have rings - made of chunks of ice and rock - but none are as spectacular or as complicated as Saturn's. Like the other gas giants, Saturn is mostly a massive ball of hydrogen and helium.
