Ymir (moon)
From Wikipedia, the free encyclopedia
Ymir (ee'-mər, IPA: [ˈiːmr̩]), or Saturn XIX, is a natural satellite of Saturn. It was discovered by Brett J. Gladman, et al. in 2000, and given the temporary designation S/2000 S 1. Ymir is about 16 kilometres in diameter, and orbits Saturn at an average distance of 23,175 Mm in 1317.137 days, at an inclination of 172° to the ecliptic (154° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.358.
Its name comes from Norse mythology, where Ymir is the ancestor of all the Jotuns or frost giants.
