S/2022 J 2

S/2022 J 2 is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard on 15 October 2022 using the 6.5-meter Magellan-Baade Telescope at Las Campanas Observatory, Chile. It was announced by the Minor Planet Center on 22 February 2023, after observations were collected over a long enough time span to confirm the satellite's orbit.

S/2022 J 2 is part of the Carme group, a tight cluster of retrograde irregular moons of Jupiter that follow similar orbits to Carme at semi-major axes between 22–24 e6km, orbital eccentricities between 0.2 and 0.3, and inclinations between 163 and 166°. With a diameter of about 1 km for an absolute magnitude of 17.5, it is one of Jupiter's smallest known moons with confirmed orbits.
