[37] [2] These discoveries brought Saturn's total number of confirmed moons up to 145, making it the first planet known to have over 100 moons. [37] [38] [39] Yet another moon, S/2006 S 20, was announced on 23 May 2023, bringing Saturn's total count moons to 146. [2]
Titan is one of seven gravitationally rounded moons of Saturn and the second-most distant among them. Frequently described as a planet-like moon, Titan is 50% larger in diameter than Earth's Moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter's Ganymede and is larger than Mercury; yet Titan is only 40% as ...
10.2 [13] Tethys (/ ˈtiːθɪs, ˈtɛθɪs /), 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. Tethys has a low density of 0.98 g/cm 3, the lowest of all the major moons in the solar ...
Saturn's second-largest moon, Rhea, may have a tenuous ring system of its own, [102] along with a tenuous atmosphere. [103] [104] [105] Many of the other moons are small: 131 are less than 50 km in diameter. [106] Traditionally, most of Saturn's moons have been named after Titans of Greek mythology.
Rhea (/ ˈriː.ə /) is the second-largest moon of Saturn and the ninth-largest moon in the Solar System, with a surface area that is comparable to the area of Australia. It is the smallest body in the Solar System for which precise measurements have confirmed a shape consistent with hydrostatic equilibrium. Rhea has a nearly circular orbit ...

Dione (moon) Dione (/ daɪˈoʊni /), also designated Saturn IV, is the fourth-largest moon of Saturn. With a mean diameter of 1,123 km and a density of about 1.48 g/cm 3, Dione is composed of an icy mantle and crust overlying a silicate rocky core, with rock and water ice roughly equal in mass. Its trailing hemisphere is marked by large cliffs ...
Pan is the innermost named moon of Saturn. [ 4 ] It is a small, ravioli [ 5 ] -shaped moon approximately 35 kilometres across and 23 km wide that orbits within the Encke Gap in Saturn's A Ring. Pan is a ring shepherd and is responsible for keeping the Encke Gap free of ring particles. It is sometimes described as having the appearance of a walnut.
