Saturn is the only planet of the Solar System that is less dense than water—about 30% less. [ 39] Although Saturn's core is considerably denser than water, the average specific density of the planet is 0.69 g/cm3, because of the atmosphere. Jupiter has 318 times Earth's mass, [ 40] and Saturn is 95 times Earth's mass. [ 6]
The rings of Saturn are the most extensive and complex ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, [ 1] that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material.
An annotated picture of Saturn 's many moons captured by the Cassini spacecraft. Shown in the image are Dione, Enceladus, Epimetheus, Prometheus, Mimas, Rhea, Janus, Tethys and Titan. The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan, which is larger than the planet Mercury ...
NASA's Cassini spacecraft, which explored Saturn and its icy moons, including the majestic Titan, ended its mission with a death plunge into the giant ringed planet in 2017. Cassini's radar ...
The Jupiter and Saturn square, occurring on Aug. 19, will create some major push and pull energy as the two planets clash ... Meaning, Jupiter is a favorable and expensive planet, while Saturn is ...
The outer planets Jupiter, Saturn, Uranus and Neptune, compared to the inner planets Earth, Venus, Mars, and Mercury at the bottom right The four outer planets, called giant planets or Jovian planets, collectively make up 99% of the mass known to orbit the Sun. [ h ] All four giant planets have multiple moons and a ring system, although only ...
Saturn imaged in 2021 through a 6" telescope, dimly showing the polar hexagon. Saturn's polar hexagon was discovered by David Godfrey in 1987 [14] from piecing together fly-by views from the 1981 Voyager mission, [15] [16] and was revisited in 2006 by the Cassini mission.
Saturn was first visited by Pioneer 11in September 1979. It flew within 20,000 kilometres (12,000 mi) of the top of the planet's cloud layer. Low-resolution images were acquired of the planet and a few of its moons; the resolution of the images was not good enough to discern surface features. The spacecraft also studied the rings; among the ...
