All known dwarf planets and dwarf planet candidates have prograde orbits around the Sun, but some have retrograde rotation. Pluto has retrograde rotation; its axial tilt is approximately 120 degrees. [9] Pluto and its moon Charon are tidally locked to each other. It is suspected that the Plutonian satellite system was created by a massive ...
The prograde satellites consist of the Himalia group and three others in groups of one. The retrograde moons are grouped into the Carme, Ananke and Pasiphae groups. 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.
Gravitational accelerations at L 4. The Hill sphere is the region in which an astronomical body dominates the attraction of satellites. Of the Solar System planets, Neptune and Uranus have the largest Hill spheres, due to the lessened gravitational influence of the Sun at their far orbits, however all of the giant planets have Hill spheres in the vicinity of 100 million kilometres in radius.
The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter
The inclination and semi-major axis are represented on the Y and X-axis, respectively. The satellites with inclinations below 90° are prograde, those above 90° are retrograde. 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.
Two prograde moons of Saturn do not definitively belong to either the Inuit or Gallic groups. [1] S/2004 S 24 and S/2006 S 12 have similar orbital inclinations as the Gallic group, but have much more distant orbits with semi-major axes of ~400 Saturn radii and ~340 Saturn radii, respectively.

All planets are direct at the start of 2024, from late January to April. ... This summer, five planets in the sky will be retrograde at the same time: Mercury, Saturn, Jupiter, Pluto, and Neptune ...
S/2020 S 1 is about 3.75 kilometers in diameter, and orbits Saturn at a distance of 11.339 Gm in 451.10 days, at an inclination of 48.2°, orbits in prograde direction and eccentricity of 0.337. [2] S/2020 S 1 belongs to the Inuit group and it may be a Kiviuq and/or Ijiraq fragment that broke off long ago, since it shares the same orbital elements.
