An annotated picture of Saturn's many moons captured by the Cassini spacecraft. Shown in the image are Dione, Enceladus, Epimetheus, Prometheus, Mimas, Rhea, Janus, Tethys and Titan. The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan, which is larger than the planet Mercury.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...

The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter
Titan is the largest moon of Saturn and the second-largest in the Solar System.It is the only moon known to have an atmosphere denser than the Earth's and is the only known object in space—other than Earth—on which there is clear evidence that stable bodies of liquid exist.
Rhea (/ ˈ r iː. 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.
Dione (/ d aɪ ˈ oʊ n i /), 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.
