Skathi (skaadh'-ee, with a voiced th as in this) (Saturn XXVII) is a natural satellite of Saturn. It was discovered by Kavelaars, et al. in 2000, and given the temporary designation S/2000 S 8. Skathi is about 6.4 kilometres in diameter, and orbits Saturn at an average distance of 15,576 Mm in 725.784 days, at an inclination of 149° to the ecliptic (154° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.246.
The name is given as Skadi by most sources. This is the name that was originally announced in IAU Circular 8177 (http://cfa-www.harvard.edu/iauc/08100/08177.html), however the IAU Working Group on Planetary System Nomenclature (WGPSN) later decided to use an alternative transliteration of the Norse spelling. The classical spelling is Skaði, with the letter Ð (eth), and the original form Skadi was a graphic approximation of that.
Skathi may have been formed from debris knocked off of Phoebe by large impacts at some point in the solar system's history.
Its name comes from Norse mythology, where Skaði is a giantess who is the wife of the Vanir god Niord.
