    S/2019 S 11 is a small and faint irregular satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Edward Ashton, Brett J. Gladman, Jean-Marc Petit and Mike Alexandersen on May 8, 2023 from observations taken between January 5, 2005 and August 16, 2020. [2]

    Physical Characteristics, Orbit and Origin

    S/2019 S 11 orbits Saturn at a distance of 20.519 Gm in 1,097.33 days, inclination of 150.6, orbits in a retrograde motion and eccentricity of 0.577. [2] S/2019 S 11 belongs to the Norse group and one of the moons that have lower inclination. [3] S/2019 S 11 leads among the furthest moons from Saturn due to its high eccentricity. [4] Which it may have a similar origin with Narvi as both moons have lower inclination. [3]

    S/2019 S 11 is estmiated to be 4 kilometers in diameter.
