Kiviuq (moon)
moon of Saturn

Kiviuq is a prograde irregular satellite of Saturn. It was discovered by JJ Kavelaars et al. in 2000, and given the temporary designation S/2000 S 5. It was named after Kiviuq, a hero of Inuit mythology.
Kiviuq is about 17 km in diameter, and orbits Saturn at an average distance of 11.3 million kilometers in 449 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.
Kiviuq is believed to be in Kozai resonance, cyclically reducing its orbital inclination while increasing the eccentricity and vice versa. Its current orbital elements overlap strongly with Phoebe's orbit, and the moons will likely eventually collide with each other.
The light curve amplitude of Kiviuq is large, varying in brightness by over 2 magnitudes.
The public source identifies “Kiviuq (moon)” as moon of Saturn. This brief keeps that definition visible, then builds a research path around Kiviuq, moon and Saturn.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Kiviuq (moon)”, the useful work is to connect “moon of Saturn” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q17965. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
