S/2017 J 11
S/2017 J 11 is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard on 25 March 2017, using the 6.5-meter Magellan-Baade Telescope at Las Campanas Observatory, Chile. It was announced by the Minor Planet Center on 30 April 2025.
S/2017 J 11 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 million km, orbital eccentricities between 0.1 and 0.3, and inclinations between 163 and 166°. It has a diameter of about 1 km for an absolute magnitude of 17.0, making it one of Jupiter's smallest known moons.
