S/2018 J 2

S/2018 J 2 is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard on 12 May 2018, using the 4.0-meter Víctor M. Blanco Telescope at Cerro Tololo Observatory, Chile. It was announced by the Minor Planet Center four years later on 20 December 2022, after observations were collected over a long enough time span to confirm the satellite's orbit. The satellite has been found in precovery observations as early as 27 March 2003.

S/2018 J 2 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 11–12 e6km and inclinations between 26–31°. With an estimated diameter of 3 km for an absolute magnitude of 16.5, it is among the smallest known members of the Himalia group.
