Sheppard, et al. in 2001, and given the temporary designation S/2001 J 11. Aitne is about 3 kilometres in diameter, and orbits Jupiter at an average distance of 22,285 Mm in 679.641 days, at an inclination of 166° to the ecliptic (164° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.393.

It 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°.
