Kiviuq is a prograde irregular satelliteofSaturn. It was discovered by Brett J. Gladman in 2000, and given the temporary designation S/2000 S 5.[7][8] It was named after Kiviuq, a hero of Inuit mythology.[9]
Kiviuq is about 16–17 km 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. It is light red, and the Kiviupian (Kiviuqan) infrared spectrum is very similar to the Inuit-group satellites Siarnaq and Paaliaq, supporting the thesis of a possible common origin of the Inuit group in the break-up of a larger body.[6][10]
Kiviuq is believed to be in Kozai resonance, cyclically reducing its orbital inclination while increasing the eccentricity and vice versa.[11]
The light curve amplitude of Kiviuq is large, varying in brightness by over 2 magnitudes. The large amplitude of Kiviuq suggests that it has an elongated shape, and may be a possible contact binary.[2]
On 30 August 2010, the ISS camera of the Cassini–Huygens spacecraft took light-curve data from a distance of 9.3 million km. With these data, the rotation period was measured to 21 hours and 49 minutes.[4]
