S/2017 J 10

S/2017 J 10 is a small outer natural satellite of Jupiter discovered by Scott S. Sheppard on 23 March 2017, using the 4.0-meter Víctor M. Blanco Telescope at Cerro Tololo Observatory, Chile. It was announced by the Minor Planet Center on 30 April 2025, after observations were collected over a long enough time span to confirm the satellite's orbit.
S/2017 J 10 is part of the Ananke group, a cluster of retrograde irregular moons of Jupiter that follow similar orbits to Ananke at semi-major axes between 19–22 million km, orbital eccentricities between 0.1 and 0.4, and inclinations between 139 and 155°. It has a diameter of about 1 km for an absolute magnitude of 17.0.
