    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 1 May 2007 from observations taken between 18 January and 19 April 2007.

    S/2007 S 3 is about 5 kilometres in diameter, and orbits Saturn at an average distance of 19,429,000 kilometres in about 1,011 days, at an inclination of 176.6° to the ecliptic, in a retrograde direction and with an eccentricity of 0.143. [2] [4]

    This moon was considered lost [5] until its recovery was announced on 12 October 2022. [2]

    S/2003 J 2 is a retrograde irregular satellite of Jupiter. The moon was discovered on 5 February 2003 by a team of astronomers from the University of Hawaii led by Scott S. Sheppard and David C. Jewitt, and was later announced on 4 March 2003. It was initially thought to be Jupiter's outermost known moon until recovery observations disproved this in 2020.
