S/2011 J 3
S/2011 J 3 is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard on 27 September 2011, using the 6.5-meter Magellan-Baade Telescope at Las Campanas Observatory, Chile. It was announced by the Minor Planet Center 11 years later on 20 December 2022, after observations were collected over a long enough time span to confirm the satellite's orbit. S/2011 J 3 is part of the Himalia group, a tight cluster of prograde irregular moons of Jupiter that follow similar orbits to Himalia at semi-major axes between  and inclinations between 26–31°. With an estimated diameter of  for an absolute magnitude of 16.3, it is among the smallest known members of the Himalia group. References
