Titan, at 5,149 km diameter, is the second largest moon in the Solar System and Saturn's largest. [68] [44] Out of all the large moons, Titan is the only one with a dense (surface pressure of 1.5 atm), cold atmosphere, primarily made of nitrogen with a small fraction of methane. [69]
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
Including these large moons, 24 of Saturn's moons are regular, and traditionally named after Titans or other figures associated with the mythological Saturn. The remaining 122 are irregular, and classified by their orbital characteristics into Inuit , Norse , and Gallic groups, and their names are chosen from the corresponding mythologies the ...

Iapetus (/ aɪ ˈ æ p ə t ə s /) is the outermost of Saturn's large moons. With an estimated diameter of 1,469 km (913 mi), it is the third-largest moon of Saturn and the eleventh-largest in the Solar System. [a] Named after the Titan Iapetus, the moon was discovered in 1671 by Giovanni Domenico Cassini.
The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter
This is smaller than the largest natural satellite that is known not to be gravitationally rounded, Neptune VIII Proteus (radius 210 ± 7 km). Several of these were once in equilibrium but are no longer: these include Earth's moon [77] and all of the moons listed for Saturn apart from Titan and Rhea. [55]
Mimas is the seventh-largest moon of Saturn, which all told has well over 100 moons ranging from Titan - larger than the planet Mercury - to some only the size of a city block.
