    S/2020 S 3 is a natural satellite of Saturn. Its discovery was announced by Edward Ashton, Brett J. Gladman, Jean-Marc Petit and Mike Alexandersen on May 5, 2023 from observations taken between July 3, 2019 and July 9, 2021. [2]

    S/2020 S 3 is about 3 kilometers in diameter, and orbits Saturn at a distance of 17.930 Gm in 896.35 days, at an inclination of 47.1, orbits in a prograde direction and with an eccentricity of 0.038. [2] S/2020 S 3 belongs to the Inuit group, it may be a Siarnaq fragment that broke off long ago, since it shares the same orbital elements and its orbit is quite circular due to its low eccentricity unlike the other irregular moons.
