Paaliaq (// PAH-lee-ahk) is a prograde irregular satellite of Saturn. It was discovered by Brett J. Gladman, John J. Kavelaars, Jean-Marc Petit, Hans Scholl, Matthew J. Holman, Brian G. Marsden, Philip D. Nicholson and Joseph A. Burns in early October 2000, and given the temporary designation S/2000 S 2. It was named in August 2003 after a fictional shaman in the book The Curse of the Shaman, written by Michael Kusugak, who supplied Kavelaars with the names of giants from Inuit mythology that were used for other Saturnian moons.
Paaliaq is thought to be about 22 kilometres in diameter, and orbits Saturn at an average distance of 15.2 Gm in 687 days. It is a member of the Inuit group of irregular satellites. It also has a proximity with 9 other moons reaching up to ten miles from each.
It is light red in color, and in the infrared the Paaliap (Paaliaqan) spectrum is very similar to the Inuit-group satellites Kiviuq and Siarnaq, supporting the thesis of a possible common origin of the Inuit group in the break-up of a larger body.
