The discovery of Skoll by Scott S. Sheppard , David C. Jewitt , Jan Kleyna and Brian G. Marsden on recordings from January 5 to April 30, 2006 was announced on June 26, 2006.
Skoll was initially given the provisional designation S / 2006 S 8. In April 2007, the moon was named after the giant wolf Skalli (also Skoll), a son of the Fenris wolf and twin brother of the giant wolf Hati , from Nordic mythology .
Structure and physical data
Skoll has a diameter of about 6 km.
Space probe observations
On November 9 and 10, 2013, the ISS camera of the Cassini space probe captured 252 images over a period of 36.5 hours, of which only about 30% were received due to heavy rain and wind in the region around the receiving station near Canberra could become. The distance between Cassini and Skoll was 11.5 million kilometers; at a phase angle of 42 °, the moon of Saturn reached a brightness of 15.5 mag . Another observation of about 30 hours took place on February 22, 2016; With this data, the rotation period could then be determined with certainty. From Earth, Skoll is about 4000 times darker at a brightness of 24.5 mag and can only be observed with large telescopes.
