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 prograde direction and 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 of its low eccentricity unlike the other irregular moons.[3]
