The discovery of Skoll by Scott S. Sheppard, David C. Jewitt Jan and Brian G. Marsden on Kleyna recordings on January 5, it was announced on 26 June 2006 to 30 April 2006. Skoll first received the provisional designation S/2006 S 8 In April 2007, the moon was then after the giant wolf Skalli (also Skoll ), a son of Fenriswolfes and twin brother of the giant wolf Hati, named from Norse mythology.

Observations with space probes

On 9 and 10 November 2013 were obtained 252 recordings by the ISS camera of the Cassini spacecraft over a period of 36.5 hours, of which only receive about 30 % due to heavy rain and wind in the region around the receiving station in Canberra could be. The distance between Cassini and Skoll was 11.5 million kilometers; at a phase angle of 42 ° of Saturn's moon reached a brightness of 15.5 mag. From Earth, Skoll is at a brightness of 24.5 like about 4000x darker and observable only with large telescopes.
