    Isonoe is about 3.8 kilometres in diameter, and orbits Jupiter at an average distance of 23,833,000 Km in 751.647 days, at an inclination of 166° to the ecliptic (169° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.166.

    It was named in October 2002 after Isonoe, one of the Danaïdes in Greek mythology, and a lover of Zeus (Jupiter).[4]

    Isonoe belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm and at an inclination of about 165°.
