    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.[4][1]

    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.[3]

    This moon was considered lost[5][6] until its recovery was announced on 12 October 2022.[2]
