Jupiter LV is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 20.220 Gm in 604.99 days, at an inclination of 143° to the ecliptic (145° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.0509.^[4]

It belongs to the Ananke group, retrograde irregular moons that orbit Jupiter between 22.8 and 24.1 Gm, at inclinations of roughly 150-155°.
