Skoll (pronounced /ˈskɒl/ skol, or as Norse IPA: [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. [4][2]

Skoll is about 6 kilometres in diameter (assuming an albedo of 0.04)[3], 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[5] after Sköll, a giant wolf from Norse mythology, son of Fenrisulfr and twin brother of Hati.
