{{nowrap|S/2003 J 10}} is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard et al. in 2003.[http://cbat.eps.harvard.edu/iauc/08000/08089.html IAUC 8089: Satellites of Jupiter] 2003 March 7 (discovery)[http://www.minorplanetcenter.net/mpec/K03/K03E29.html MPEC 2003-E29: S/2003 J 9, 2003 J 10, 2003 J 11, 2003 J 12; S/2003 J 1, 2003 J 6] 2003 April 3 (discovery and ephemeris)

{{nowrap|S/2003 J 10}} is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 22,857,000 km in approximately 706 days, at an inclination of 163° to the ecliptic, in a retrograde direction and with an eccentricity of 0.34.

It belongs to the Carme group.
