S/2006 S 3 is about 6 kilometres in diameter, and orbits Saturn at an average distance of 21,308,400 km in 1160.7 days, at an inclination of 152.8° to the ecliptic, in a retrograde direction and with an eccentricity of 0.4707.[3]

The moon was once considered lost in 2006 as it was not seen since its discovery.[4][5][6] The moon was later recovered and announced in October 2019.[3]
