Norse Group
The Norse group is a large group of retrograde irregular satellites of Saturn. Their semi-major axes range between 12 and 24 Gm, their inclinations between 136° and 175° and their eccentricities between 0.13 and 0.77. Unlike for the Inuit and Gallic groups, the orbital parameters are widely dispersed and group is likely to be composed from a number of subgroups with more homogenous orbital and physical parameters. For example, the satellites with inclinations around 174 degrees alone are thought to comprise at least two subgroups. Eight other moons form the Skathi subgroup. Their semi-major axes range between 15 and 20 Gm, their inclinations between 147° and 158°. Narvi forms a separate subgroup with Bestla. The International Astronomical Union (IAU) reserves names taken from Norse mythology (mostly giants) for these moons. The exception is Phoebe (Greek mythology), the largest, which was discovered long before the others. The discovery of 17 new moons in this group wa ...

Skoll (moon)
Skoll or Saturn XLVII (provisional designation S/2006 S 8) is a retrograde irregular satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt and Jan Kleyna on 26 June 2006 from observations taken between 5 January and 30 April 2006. Skoll is about 6 kilometres in diameter (assuming an albedo of 0.04) and orbits Saturn at an average distance of 17.6 Gm (million km) in 869 days, following a highly eccentric and moderately inclined orbit. A rotation period of was obtained by ''Cassini–Huygens'' in 2016, but this is in strong disagreement with 2013 data for unknown reasons; one possible explanation is variation in the rotation speed and axis due to Milankovitch wobble. It was named in April 2007 after Sköll, a giant wolf from Norse mythology, son of Fenrir Fenrir (Old Norse: ; "fen-dweller")Orchard (1997:42). or Fenrisúlfr (O.N.: ; "Fenrir's wolf", often translated "Fenris-wolf"),Simek (2007:81). also referred to as Hróðvitnir (O.N.: ; ...

Marsden on 4 May 2005, from observations taken between 12 December 2004 and 11 March 2005. Hati is about 6 kilometers in diameter, and orbits Saturn at an average distance of 20,303 Mm in 1080 days, at an inclination of 163° to the ecliptic (165° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.291. In March 2013, the synodic rotational period was measured by '' Cassini'' to about hours. This is the fastest known rotation of all of Saturn's moons. It was named in April 2007 after Hati, a giant wolf from Norse mythology, son of Fenrisúlfr and twin brother of Sköll In Norse mythology, Sköll (Old Norse: ''Skǫll'', "Treachery"Orchard (1997:150). or "Mockery"Simek (2007:292)) is a wolf that, according to Snorri Sturluson's ''Prose Edda'', chases the Sun (personified as a goddess, Sól).

Bergelmir (moon)
Bergelmir or Saturn XXXVIII (provisional designation S/2004 S 15) is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on May 4, 2005, from observations taken between December 12, 2004, and March 9, 2005.

Bergelmir and his wife alone among their kind were the only survivors of the enormous deluge of blood from Ymir's wounds when he was killed by Odin and his brothers at the dawn of time. Bergelmir then became the progenitor of a new race of giants. References External links Institute for Astronomy Satur ...

Narvi (moon)
Narvi or Saturn XXXI is a natural satellite of Saturn. It was discovered by a team of astronomers led by Scott S. Sheppard in 2003, and given the temporary designation S/2003 S 1. Description Narvi is about 7 kilometres in diameter, and orbits Saturn at an average distance of 19,371,000 km in 1006.541 days, at an inclination of 136.8° to the ecliptic (109° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.2990, very similar to Bestla's orbit. Narvi's rotation period is hours, and its light curve has three minima like Siarnaq and Ymir.
