Saturn is named after the Roman god of wealth and agriculture, who was the father of the god Jupiter.Its astronomical symbol has been traced back to the Greek Oxyrhynchus Papyri, where it can be seen to be a Greek kappa-rho ligature with a horizontal stroke, as an abbreviation for Κρονος (), the Greek name for the planet ().

The hexagon may be a bit more than 29,000 km (18,000 mi) wide, [9] may be 300 km (190 mi) high, and may be a jet stream made of atmospheric gases moving at 320 km/h (200 mph). [ 4 ] [ 5 ] [ 10 ] It rotates with a period of 10h 39m 24s , the same period as Saturn's radio emissions from its interior. [ 11 ]

It is a gas giant with an average radius about nine times that of Earth. [1] [2] Although only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive. [3] [4] Saturn is named after the Roman god of agriculture; its astronomical symbol (♄) represents the god's sickle.
The smallest known extrasolar planet that is likely a "gas planet" is Kepler-138d, which has the same mass as Earth but is 60% larger and therefore has a density that indicates a thick gas envelope. [16] A low-mass gas planet can still have a radius resembling that of a gas giant if it has the right temperature. [17]
They differ from the terrestrial planets in composition. The gas giants, Jupiter and Saturn, are primarily composed of hydrogen and helium and are the most massive planets in the Solar System. Saturn is one third as massive as Jupiter, at 95 Earth masses. [31]
About 25% of its mass, NASA estimates, is made up of water. Saturn’s moon Enceladus, with a 313-mile diameter, regularly emits icy geysers, produced when oceans beneath its crust are squeezed by ...
For example, Venus is approximately 0.33 AU farther out from the Sun than Mercury, whereas Saturn is 4.3 AU out from Jupiter, and Neptune lies 10.5 AU out from Uranus. Attempts have been made to determine a relationship between these orbital distances, like the Titius–Bode law [ 60 ] and Johannes Kepler's model based on the Platonic solids ...
