S/2017 J 3 is an outer natural satellite of Jupiter. It was discovered by Scott S. Sheppard and his team in 2017, but not announced until July 17, 2018 via a Minor Planet Electronic Circular from the Minor Planet Center.[2] It is about 2 kilometers in diameter and orbits at a semi-major axis of about 20,694,000 km with an inclination of about 147.9°. It belongs to the Ananke group.[1]
