S/2004 S 7 is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 4 May 2005 from observations taken between 12 December 2004 and 8 March 2005.
S/2004 S 7 is about 6 kilometres in diameter, and orbits Saturn at an average distance of 21,559,000 kilometres in about 1,182 days, at an inclination of 165.0° to the ecliptic, in a retrograde direction and with an eccentricity of 0.574. Denk et al. (2018) tentatively assigned this moon to the Mundilfari dynamical family, but it may instead be more closely related to Thrymr.[1]
This moon was considered lost[2] until its recovery was announced on 12 October 2022.
