Saturn's Gallic Group Of Satellites
The Gallic group is a dynamical grouping of the Retrograde and prograde motion, prograde irregular satellites of Saturn following similar orbits. Their semi-major axis, semi-major axes range between 16 and 19 Gm, their inclinations between 36° and 41°, and their Orbital eccentricity, eccentricities between 0.46 and 0.53. The International Astronomical Union (IAU) reserves names taken from Celtic mythology, Gallic mythology for these moons. Similar mean orbital elements led the discoverers to postulate a common origin for the group in a breakup of a larger body. The group was later found to be physically homogeneous, all satellites displaying ''light-red'' colour (color index, colour indices B − V = 0.91 and V − R = 0.48) and similar infrared indices. Remarkably, recent observations revealed that the largest member of the group, Albiorix (moon), Albiorix, actually displays two different colours: one compatible with Erriapus and Tarvos (moon), Tarvos, and another less red.

Animation Of Saturn's Gallic Group Of Satellites
Animation is a filmmaking technique whereby image, still images are manipulated to create Motion picture, moving images. In traditional animation, images are drawn or painted by hand on cel, transparent celluloid sheets to be photographed and exhibited on film. Animation has been recognised as an artistic medium, specifically within the Entertainment#Industry, entertainment industry. Many animations are either traditional animations or computer animations made with computer-generated imagery (CGI). Stop motion animation, in particular claymation, has continued to exist alongside these other forms. Animation is contrasted with live action, although the two do not exist in isolation. Many moviemakers have produced Live-action animation, films that are a hybrid of the two. As CGI increasingly Photorealism, approximates photographic imagery, filmmakers can easily Compositing, composite 3D animations into their film rather than using practical effects for showy visual effects (VFX). ...

Erriapus
Erriapus , or Saturn XXVIII (28), is a prograde irregular satellite of Saturn. It was discovered by Brett Gladman, John J. Kavelaars and colleagues in 2000, and given the temporary designation S/2000 S 10. It was named Erriapo in August 2003 after ''Erriapus'' (also rendered ''Erriappus''), a giant in Gaulish mythology; the name was changed from dative ''Erriapo'' to nominative ''Erriapus'' per IAU conventions in late 2007. Erriapus is about 10 kilometres in diameter, and orbits Saturn at an average distance of 17.5 Gm in 871 days. As a member of the Gallic group of irregular satellites, which share similar orbital characteristics and a light-red colour, Erriapus is hypothesized to have its origin in the break-up of a common progenitor of the group, or to be a fragment of its largest member, Albiorix. It has a rotation period of , and is thought to rotate on its side, giving it similar seasons to those of Uranus. With a fairly elongated shape, it is a candid ...

Moons Of Saturn
The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan (moon), Titan, which is larger than the planet Mercury (planet), Mercury. There are 274 natural satellite, moons with confirmed orbits, the most of any planet in the Solar System. This number does not include the many thousands of moonlets embedded within Rings of Saturn, Saturn's dense rings, nor hundreds of possible kilometer-sized distant moons that have been observed on single occasions. Three moons are particularly notable. Titan is the second-List of natural satellites, largest moon in the Solar System (after Jupiter's Ganymede (moon), Ganymede), with a Atmosphere of Titan#Composition, nitrogen-rich Earth-like Atmosphere of Titan, atmosphere and a landscape featuring river networks and lakes of Titan, hydrocarbon lakes. Enceladus emits jets of ice from its south-polar region and is covered in a deep layer of snow. Iapetus (moon), Iapetus has contrasting ...

Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a Federally funded research and development centers, federally funded research and development center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States. Founded in 1936 by California Institute of Technology (Caltech) researchers, the laboratory is now owned and sponsored by NASA and administered and managed by Caltech. The primary function of the laboratory is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network (DSN). Among the major active projects at the laboratory, some are the Mars 2020 mission, which includes the ''Perseverance (rover), Perseverance'' rover; the Mars Science Laboratory mission, including the ''Curiosity (rover), Curiosity'' rover; the ''Mars Reconnaissance Orbiter''; the ''Juno (spacecraft), Juno'' spacecraft orbiting Jupiter; the ''Soil Moisture Active P ...

List Of Natural Satellites
Of the Solar System's eight planets and its list of possible dwarf planets, nine most likely dwarf planets, six planets and seven dwarf planets are known to be orbited by at least 430 natural satellites, or moons. At least List of gravitationally rounded objects of the Solar System#Satellites, 19 of them are large enough to be gravitationally rounded; of these, all are covered by a Crust (geology), crust of ice except for Earth's Moon and Jupiter's Io (moon), Io. Several of the largest ones are in hydrostatic equilibrium and would therefore be considered dwarf planets or planets if they were in direct orbit around the Sun and not in their current states (orbiting planets or dwarf planets). Moons are classed into two separate categories according to their orbits: regular moon, regular moons, which have prograde orbits (they orbit in the direction of their planets' rotation) and lie close to the plane of their equators, and irregular moon, irregular moons, whose orbits can be pro- ...

S/2020 S 4
S/2020 S 4 is a small and very faint natural satellite of Saturn. It was discovered by Edward Ashton, Brett J. Gladman, Jean-Marc Petit and Mike Alexandersen on June 24, 2020, and was announced on May 6, 2023 by the IAU Minor Planet Center after observations were collected over a long period of time to confirm the satellite's orbit that were taken between July 1, 2019 and July 9, 2021. Orbit S/2020 S 4 is a highly eccentric satellite with an eccentricity of 0.495, it orbits Saturn at an average distance of 18.2 million km and an orbital period of 2 and a half years, with an inclination of 40.1° to the ecliptic, suggesting that it belongs to the Gallic group. However, sometimes its moon group is disputed, and it may be included in the Inuit group. It has been suggested that it was a fragment piece of Siarnaq that broke off a long time ago in a time-span of a few thousand years. The orbit of S/2020 S 4 is liberating in accordance of von Zeipel–Lidov–Kozai effect. Physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

S/2004 S 24
S/2004 S 24 is a natural satellite of Saturn, and the outermost known prograde satellite. 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. S/2004 S 24 is about 3 kilometres in diameter, and orbits Saturn at an average distance of 22.901 Gm in 1294.25 days, at an inclination of 35.5° to the ecliptic, in a prograde direction and with an eccentricity of 0.085. Due to its inclination being similar to members of the Gallic group 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 0.4 ..., S/2004 S 24 could belong to the Gallic group. However, its orbit is much more distant, which puts this classification into question. It could very well be in a group of its own. The exac ...
