S/2020 S 5 is a natural satellite of Saturn. Its discovery was announced by Edward Ashton, Brett J. Gladman, Jean-Marc Petit and Mike Alexandersen on May 6, 2023 from observations taken between July 3, 2019 and July 9, 2021.[2]
S/2020 S 5 is about 3 kilometers in diameter, and orbits Saturn at a distance of 18.422 Gm in 933.52 days, at an inclination of 49.41, orbits in prograde direction and eccentricity of 0.135.[2] S/2020 S 5 belongs to the Inuit group and it may be a Siarnaq fragment that broke off long ago, since it shares the same orbital elements.[3]
