Pandia /pænˈdaɪə/, also designated Jupiter LXV, is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard on 11 May 2018, using the 4.0-meter Víctor M. Blanco Telescope at Cerro Tololo Observatory, Chile. It was announced alongside nine other Jovian moons on 17 July 2018 and it provisionally designated S/2017 J 4 by the Minor Planet Center, after observations were collected over a long enough time span to confirm the satellite's orbit.[1] The satellite has been found in precovery observations as early as 2003.[citation needed]
Pandia 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 million km (6.8–7.5 million mi) and inclinations between 26–31°.[5] With an estimated diameter of 3 km (1.9 mi) for an absolute magnitude of 16.2, it is one of the smallest known members of the Himalia group.[5]
