Iapetus is the third-largest of Saturn's moons. [53] Orbiting the planet at 3.5 million km, it is by far the most distant of Saturn's large moons, and also has the largest orbital inclination, at 15.47°. [45]
Saturn has 146 moons with known orbits; 66 of them have received permanent designations, and 63 have been named. Most of them are quite small. Seven moons are large enough to be in hydrostatic equilibrium, including Titan, the second largest moon in the Solar System.
Many of the other moons are small: 131 are less than 50 km in diameter. [105] Traditionally, most of Saturn's moons have been named after Titans of Greek mythology. Titan is the only satellite in the Solar System with a major atmosphere, [106] [107] in which a complex organic chemistry occurs.
Saturn III Saturn I (1686–1789) Cassini [15] Together with his previous two discoveries, Cassini named these satellites Sidera Lodoicea. In his work Kosmotheôros [16] (published posthumously in 1698), Christiaan Huygens relates "Jupiter you see has his four, and Saturn his five Moons about him, all plac’d in their Orbits."

The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter 20 new moons were discovered around Saturn Skip to main content
Titan orbits Saturn at 20 Saturn radii or 1,200,000 km above Saturn's apparent surface. From Titan's surface, Saturn, disregarding its rings, subtends an arc of 5.09 degrees, and if it were visible through the moon's thick atmosphere, it would appear 11.4 times larger in the sky, in diameter, than the Moon from Earth, which subtends 0.48° of arc.
Mimas, one of Saturn’s many moons, is best known for Herschel crater, which sci-fi buffs will attest makes the moon look like a dollar-store version of the Death Star. The real mystery? How it ...
Cassini studied Saturn and its moons for more than a decade before crashing into the planet in 2017. By closely examining the subtle changes in Mimas’s orbit, the researchers said they were able ...
