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 ().

Saturn – sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. 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.

An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam' and σφαῖρα (sphaîra) 'sphere') [1] is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
The sun passes south to north through the ring plane when Saturn's heliocentric longitude is 173.6 degrees (e.g. 11 August 2009), about the time Saturn crosses from Leo to Virgo. 15.7 years later Saturn's longitude reaches 353.6 degrees and the sun passes to the south side of the ring plane.
Map the thermal structure of Saturn's atmosphere by infrared observations coupled with radio occultation data. Obtain spin-scan images of the Saturnian system in two colors during the encounter sequence and polarimetry measurements of the planet. Probe the ring system and the atmosphere of Saturn with S-band radio occultation.
Atmospheric super-rotation is a phenomenon where a planet's atmosphere rotates faster than the planet itself. This behavior is observed in the atmospheres of Venus, Titan, Jupiter, and Saturn. Venus exhibits the most extreme super-rotation, with its atmosphere circling the planet in four Earth days, much faster than the planet's own rotation of ...
The Moon's atmosphere is extremely thin, consisting of a partial vacuum with particle densities of under 10 7 per cm −3. [115] Mars (1.38–1.67 AU) [D 6] has a radius about half of that of Earth. [116] Most of the planet is red due to iron oxide in Martian soil, [117] and the polar regions are covered in white ice caps made of water and ...
