Aitne (et'-nee, IPA: [ˈɛtni]; Greek Άιτνη), or Jupiter XXXI, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. 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 (143° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.393.
