S/2004 S 43 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 7, 2023 from observations taken between December 12, 2004 and July 9, 2021. [2]
S/2004 S 43 is about 4 kilometers in diameter, and orbits Saturn at a distance of 18.918 Gm in 971.48 days, at an inclination of 172.0, orbits in retrograde direction and eccentricity of 0.390. [2] S/2004 S 43 belongs to the Norse group and was marked the 100th moon of Saturn by count at the time it was announced. [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.
