Kiviuq (pronEng|ˈkiːvioʊk "KEE-vee-ohk," or IPAlink-en|ˈkɪviʊk "KIV-ee-ook)" is a prograde irregular satellite of Saturn. It was discovered by Brett J. Gladman in 2000, and given the temporary designation S/2000 S 5. [ [http://cfa-www.harvard.edu/iauc/07500/07521.html IAUC 7521: "S/2000 S 5, S/2000 S 6"] 2000 November 18 (discovery)] [ [http://cfa-www.harvard.edu/mpec/K00/K00Y14.html MPEC 2000-Y14: "S/2000 S 3, S/2000 S 4, S/2000 S 5, S/2000 S 6, S/2000 S 10"] 2000 December 19 (discovery and ephemeris)]

It was named in 2003 after a "giant" of Inuit mythology. [ [http://cfa-www.harvard.edu/iauc/08100/08177.html IAUC 8177: "Satellites of Jupiter, Saturn, Uranus"] 2003 August 8 (naming the moon)] Kiviuq (also spelled Keeveeok, Qiviuq or Kivioq) is a legendary and heroic Inuk, a sort of Inuit Odysseus. He has lived very long (or has had several lives), has wandered and journeyed, living all sorts of adventures whose details depend on the story-teller's local tradition.

Kiviuq is about 16 kilometres in diameter, and orbits Saturn at an average distance of 11.1 million kilometers in 450 days. It is a member of the Inuit group of irregular satellites.

Kiviuq displays "light-red" colours and the infrared spectrum very similar to Siarnaq and Paaliaq, further supporting the thesis of a possible common origin of the Inuit group in the break-up of a larger bodyGladman, B. J.; Nicholson, P. D.; Burns, J. A.; Kavelaars, J. J.; Marsden, B. G.; Holman, M. J.; Grav, T.; Hergenrother, C. W.; Petit, J.-M.; Jacobson, R. A.; and Gray, W.

Kiviuq is believed to be in Kozai resonance i.e. cyclically reducing the orbital inclination while increasing the eccentricity and "vice versa".Ćuk, M.; and Burns, J.
