Saturn's rings shine in Hubble's latest portrait

Saturn is so beautiful that astronomers cannot resist using the Hubble Space Telescope to take yearly snapshots of the ringed world when it is at its closest distance to Earth.

Making sense of Saturn's impossible rotation

Saturn may be doing a little electromagnetic shimmy and twist which has been throwing off attempts by scientists to determine how long it takes for the planet to rotate on its axis, according to a new study.

Image: Night into day on Saturn's rings

In this image by the international Cassini spacecraft, Saturn's shadow is captured creeping across the rings. The bottom half of the image shows the bright rings reflecting sunlight from their icy particles, whereas the top ...

Wind mystery inside gas giant Saturn begins to unravel

A new study argues that Saturn's interior flows like honey due to its magnetic field, which may help solve the mystery of why the planet's powerful winds stop 8,500km inside the giant gas planet.

A brief astronomical history of Saturn's amazing rings

Many dream of what they would do had they a time machine. Some would travel 100 million years back in time, when dinosaurs roamed the Earth. Not many, though, would think of taking a telescope with them, and if, having done ...

Cassini reveals new sculpting in Saturn rings

As NASA's Cassini dove close to Saturn in its final year, the spacecraft provided intricate detail on the workings of Saturn's complex rings, new analysis shows.

Saturn's moon Mimas, a snowplow in the planet's rings

The Solar System's second largest planet both in mass and size, Saturn is best known for its rings. These are divided by a wide band, the Cassini Division, whose formation was poorly understood until very recently. Now, researchers ...

See the moon photobomb saturn in an amazing capture

Welcome to Saturn as you've probably never seen it. It's always awe-inspiring to see the clockwork motion of the heavens transpire in real time. In a slow motion universe, occultations give us the chance to see the cosmos ...

Saturn

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn, along with Jupiter, Uranus and Neptune, is classified as a gas giant. Together, these four planets are sometimes referred to as the Jovian, meaning "Jupiter-like", planets.

Saturn is named after the Roman god Saturn (that became the namesake of Saturday), equated to the Greek Kronos (the Titan father of Zeus) the Babylonian Ninurta and to the Hindu Shani. Saturn's symbol represents the god's sickle (Unicode: ♄).

The planet Saturn is composed of hydrogen, with small proportions of helium and trace elements. The interior consists of a small core of rock and ice, surrounded by a thick layer of metallic hydrogen and a gaseous outer layer. The outer atmosphere is generally bland in appearance, although long-lived features can appear. Wind speeds on Saturn can reach 1,800 km/h, significantly faster than those on Jupiter. Saturn has a planetary magnetic field intermediate in strength between that of Earth and the more powerful field around Jupiter.

Saturn has a prominent system of rings, consisting mostly of ice particles with a smaller amount of rocky debris and dust. Sixty-one known moons orbit the planet, not counting hundreds of "moonlets" within the rings. Titan, Saturn's largest and the Solar System's second largest moon (after Jupiter's Ganymede), is larger than the planet Mercury and is the only moon in the Solar System to possess a significant atmosphere.
