S/2019 S 1 is a natural satellite of Saturn. Its discovery was announced by Edward Ashton, Brett J. Gladman, Jean-Marc Petit, and Mike Alexandersen on 16 November 2021 from Canada–France–Hawaii Telescope observations taken between 1 July 2019 and 14 June 2021.[1]

S/2019 S 1 is about 5 kilometres in diameter, and orbits Saturn at an average distance of 11.2 million km (7.0 million mi) in 443.78 days, at an inclination of 44° to the ecliptic, in a prograde direction and with an eccentricity of 0.623.[1] It belongs to the Inuit group of prograde irregular satellites, and is among the innermost irregular satellites of Saturn.[3] It might be a collisional fragment of Kiviuq and Ijiraq, which share very similar orbital elements.[4]

This moon's eccentric orbit takes it closer than 1.5 million km (0.93 million mi) to Iapetus several times per millennium.[4]
