S/2016 J 4 is part of thePasiphae group, a dispersed cluster of distantretrograde irregular moons of Jupiter that follow similar orbits toPasiphae atsemi-major axes between 22–25 million km (14–16 million mi),orbital eccentricities between 0.2–0.6, andinclinations between 140–160°.^[3] It has a diameter of about 1 km (0.62 mi) for anabsolute magnitude of 17.3, making it one of Jupiter's smallest known moons.^[3]
