The X-axis is labeled in terms of Saturn's Hill radius. The Gallic group is a dynamical grouping of the prograde irregular satellites of Saturn following similar orbits . Their semi-major axes range between 16 and 19 Gm, their inclinations between 36° and 41°, and their eccentricities between 0.46 and 0.53.
Saturn is named after the Roman god of wealth and agriculture, who was the father of the god Jupiter.Its astronomical symbol has been traced back to the Greek Oxyrhynchus Papyri, where it can be seen to be a Greek kappa-rho ligature with a horizontal stroke, as an abbreviation for Κρονος (), the Greek name for the planet ().

Gerd (Saturn LVII), provisionally known as S/2004 S 25, is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, and Jan Kleyna on October 7, 2019 from observations taken between December 12, 2004 and March 22, 2007. [3] It was given its permanent designation in August 2021. [4]
S/2004 S 12 is about 5 kilometres in diameter, and orbits Saturn at an average distance of 19,855,000 kilometres in about 1,044 days, at an inclination of 163.9° to the ecliptic, in a retrograde direction and with an eccentricity of 0.371. [2] [4] This moon was considered lost [5] until its recovery was announced on 12 October 2022. [2]
S/2019 S 1 is a natural satellite of Saturn. Its discovery was announced by Edward Ashton, Brett J. Gladman, Jean-Marc Petit, and Mike Alexandersen on 16 November 2021 from Canada–France–Hawaii Telescope observations taken between 1 July 2019 and 14 June 2021.

The surface of Hyperion is covered with numerous impact craters—those with diameters 2–10 km are especially abundant. [78] It is the only moon besides the small moons of Pluto known to have a chaotic rotation, which means Hyperion has no well-defined poles or equator.
The X-axis is labeled in terms of Saturn's Hill radius. The Norse group is a large group of retrograde irregular satellites of Saturn . Their semi-major axes range between 12 and 27 Gm, their inclinations between 136° and 178° and their eccentricities between 0.06 and 0.63.
