The fully processed composite photograph of Saturn taken by Cassini on July 19, 2013 Earth can be seen as a blue dot underneath the rings of Saturn. The photomosaic from NASA's "Wave at Saturn" campaign. The collage includes some 1,600 photos taken by members of the public on The Day the Earth Smiled.
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 ().

Hyperion is redder than Phoebe and closely matches the color of the dark material on Iapetus. Hyperion has a porosity of about 0.46. [9] Although Hyperion is the eighth-largest moon of Saturn, it is only the ninth-most massive. Phoebe has a smaller radius, but it is more massive than Hyperion and thus denser. [7]
It is Saturn's ninth-largest moon, but it is the eighth-most massive. Hyperion, another one of Saturn's moons, has a larger radius, but is less massive than Phoebe. Phoebe rotates every nine hours and 16 minutes, and completes a full orbit around Saturn in about 18 months. Its surface temperature is on average 75 K (−198.2 °C).
Giovanni Domenico Cassini, discoverer of Iapetus. Iapetus was discovered by Giovanni Domenico Cassini, an Italian-born French astronomer, in October 1671.This is the first moon that Cassini discovered; the second moon of Saturn to be discovered after Christaan Huygens spotted Titan 16 years prior in 1655; and the sixth extraterrestrial moon to be discovered in human history.
Tethys (/ ˈ t iː θ ɪ s, ˈ t ɛ θ ɪ s /), or Saturn III, is the fifth-largest moon of Saturn, measuring about 1,060 km (660 mi) across. It was discovered by Giovanni Domenico Cassini in 1684, and is named after the titan Tethys of Greek mythology .

Aegaeon is the smallest known moon of Saturn outside of the rings and has an extremely elongated shape, measuring 1.4 km × 0.5 km × 0.4 km (0.87 mi × 0.31 mi × 0.25 mi) in size. [9] Measurements of its mass show that Aegaeon has a very low density, likely due to a highly porous and icy interior structure. [ 5 ]
