S/2021 J 6

S/2021 J 6 is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard, David J. Tholen, and Chad Trujillo on 5 September 2021, using the 8.2-meter Subaru Telescope at Mauna Kea Observatory, Hawaii. It was announced by the Minor Planet Center on 20 January 2023, 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 2 October 2010.

S/2021 J 6 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 0.2–0.3, and inclinations between 163–166°. It has a diameter of about 1 km for an absolute magnitude of 17.3, making it one of Jupiter's smallest known moons.
