It is estimated that the A Ring contains 7,000–8,000 propellers larger than 0.8 km in size and millions larger than 0.25 km. [4] In April 2014, NASA scientists reported the possible consolidation of a new moon within the A Ring, implying that Saturn's present moons may have formed in a similar process in the past when Saturn's ring system was ...
The known icy moons in this range are all ellipsoidal (except Proteus), but trans-Neptunian objects up to 450–500 km radius may be quite porous. [10] For simplicity and comparative purposes, the values are manually calculated assuming that the bodies are all spheres. The size of solid bodies does not include an object's atmosphere.
Discovered in 1655 by the Dutch astronomer Christiaan Huygens, Titan was the first known moon of Saturn and the sixth known planetary satellite (after Earth's moon and the four Galilean moons of Jupiter). Titan orbits Saturn at 20 Saturn radii or 1,200,000 km above Saturn's apparent surface. From Titan's surface, Saturn subtends an arc of 5.09 ...
Scientists finally have a comprehensive view of Titan, Saturn's largest moon. A team of astronomers has created the first global map of Titan by using the Cassini probe's over 100 fly-bys to ...
Size comparison between Mimas (lower left), the Moon (upper left) and Earth. Mimas is the smallest and innermost of Saturn's major moons. The surface area of Mimas is slightly less than the land area of Spain or California. The low density of Mimas, 1.15 g/cm 3, indicates that it is composed mostly of water ice with only a small amount of rock.

Siarnaq, also designated Saturn XXIX, is the second-largest irregular moon of Saturn. It was discovered on 23 September 2000 by a team of astronomers led by Brett J. Gladman . It was named after the Inuit goddess of the sea, Siarnaq, who is more commonly known as Sedna .
