S/2006 S 12 is a small and faint natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, E. Ashton and Brett J. Gladman on May 7, 2023 from observations taken between January 5, 2006 and July 8, 2021.[2]
Physical Characteristics, Orbit and Origin
[edit]S/2006 S 12 orbits Saturn at an average distance of 19.569 Gm in 1,043.16 days, at an inclination of 39.03, orbits in prograde direction and eccentricity of 0.542.[2] S/2006 S 12 belongs to the Gallic group. Scott S. Sheppard suggests that S/2006 S 12 is uncertain whether it belongs to the Gallic group or an outlier like S/2004 S 24,[3] but a later study from Edward Ashton suggests that it is related to Albiorix.[4]
S/2006 S 12 is estimated to be about 4 kilometers in diameter.
