S/2004 S 13 is about 6 kilometres in diameter, and orbits Saturn at an average distance of 18,486,000 kilometres in about 938 days, at an inclination of 167.0° to the ecliptic, in a retrograde direction and with an eccentricity of 0.271. [2] [4]
This moon was considered lost [5] until its recovery was announced on 12 October 2022. [2]
