Aitne or Jupiter XXXI, is a non-spherical moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, et al. in 2001, and given the designation S/2001 J 11.
Aitne is about 3 kilometres in diameter, and orbits Jupiter at an average distance of 22,285,000 km in 679.641 days, at an inclination of 166° to the ecliptic (164° to Jupiter's equator), with an orbital eccentricity of 0.393.
It was named in August 2003 after Aitna or Aitne, the divine personification of Mount Etna, whose sons by Zeus (Jupiter) are the Palici, the twin sicilian gods of geysers (other authors have them descend from Thalia and/or Hephaistos).
