Jewitt, Jan Kleyna, and Brian G. Marsden on June 26, 2006, from observations taken between January 5 and April 29, 2006.
Jarnsaxa is about 4 kilometres in diameter, and orbits Saturn at an average distance of 18,556.9 Mm in 943.784 days, at an inclination of 162.9° to the ecliptic (164.1° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.1918.
