Skoll (pronEng|ˈskɒl "skol," or as Norse IPA2|skœlː) or Saturn XLVII (provisional designation S/2006 S 8) is a retrograde irregular satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt and Jan Kleyna on June 26, 2006, from observations taken between January 5 and April 30, 2006. [ [http://cfa-www.harvard.edu/iauc/08700/08727.html IAUC 8727: "Satellites of Saturn"] 2006 June 30 (discovery)]

Skoll is about 6 kilometres in diameter (assuming an albedo of 0.04), and orbits Saturn at an average distance of 17.6 Gm (million km) in 869 days, following a highly eccentric and moderately inclined orbit.

It was named in April 2007 [ [http://cfa-www.harvard.edu/iauc/08800/08826.html IAUC 8826: "Satellites of Jupiter and Saturn"] (subscription-only) 2007 April 5 (naming the moon)] after Sköll, a giant wolf from Norse mythology, son of Fenrisulfr and twin brother of Hati.
