S/2020 S 1 is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, Edward Ashton, Brett J. Gladman, Jean-Marc Petit and Mike Alexandersen on May 3, 2023 from observations taken between December 14, 2004 and July 8, 2021.[2]
S/2020 S 1 is about 4 kilometers in diameter, and orbits Saturn at a distance of 11.339 Gm in 450.83 days, at an inclination of 47.0, orbits in prograde direction and eccentricity of 0.462.[2] S/2020 S 1 belongs to the Inuit group and it may be a Kiviuq and/or Ijiraq fragment that broke off long ago, since it shares the same orbital elements.[3]
