    S/2020 S 1 is a 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 December 14, 2004 and July 8, 2021. [1]

    S/2020 S 1 is about 3.75 kilometers in diameter, and orbits Saturn at a distance of 11.339 Gm in 451.10 days, at an inclination of 48.2, orbits in prograde direction and eccentricity of 0.337. [2] S/2020 S 1 belongs to the Inuit group and it may be a Kiviuq and/or Ijiraq fragment that broke off long ago, since it shares the same orbital elements. [3]

    Siarnaq, also designated Saturn XXIX, is the second-largest irregular moon of Saturn. It was discovered on 23 September 2000 by a team of astronomers led by Brett J. Gladman. It was named after the Inuit goddess of the sea, Siarnaq, who is more commonly known as Sedna. Siarnaq is the largest member of Saturn's Inuit group of prograde irregular moons, which orbit far from Saturn in the same direction as the planet's rotation. The moons of the Inuit group are believed to have originated as fragments from the collisional breakup of a larger progenitor moon after it was gravitationally captured into orbit around Saturn several billion years ago. Several other small Inuit group moons share similar orbits to Siarnaq, indicating that the moon had experienced another collision after forming from its progenitor.
