S/2006 S 1 is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on June 26, 2006 from observations taken between January 4 and April 30, 2006. S/2006 S 1 is about 6 kilometres in diameter, and orbits Saturn at an average distance of 18.65 Gm in 951.1 days, at an inclination of 154.6° to the ecliptic (178.9° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.0814.[1]

The moon was once considered lost in 2006 as it was not seen since its discovery.[5][6] The moon was later recovered and announced in October 2019.[7][3]
