    S/2007 S 5 is a small and faint 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 January 5, 2005 and July 9, 2021. [2]

    Physical Characteristics, Orbit and Origin

    S/2007 S 5 and orbits Saturn at a distance of 15.836 Gm in 746.88 days, at an inclination of 158.4, orbits in a retrograde direction and with an eccentricity of 0.104. [1] S/2007 S 5 belongs to the Norse group and part of the Mundilfari subgroup. [3] The orbit of S/2007 S 5 is quite circular due to its low eccentricity unlike the other irregular moons. [4]

    S/2007 S 5 is estimated to be about 4 kilometers in diameter.
