S/2007 S 3 is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on May 1, 2007 from observations taken between January 18 and April 19, 2007. S/2007 S 3 is about 5 kilometres in diameter, and orbits Saturn at an average distance of 20,518,500 kilometres in about 1100 days, at an inclination of 177.22° to the ecliptic, in a retrograde direction and with an eccentricity of 0.130. This moon has not been seen since its discovery in 2007 and is currently considered lost.[3][4][5]
