Kiviuq (kee'-vee-oek, IPA: /ˈkiːviok/, or kiv'-ee-ook, /ˈkɪviʊk/) 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.[6][7] It was named in 2003 after a "giant" of Inuit mythology.[8] 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 body[9][5]. Kiviuq is believed to be in Kozai resonance i.e. cyclically reducing the orbital inclination while increasing the eccentricity and vice versa.[10]
