Aitne /ˈeɪtniː/, also known as Jupiter XXXI, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard in 2001, and given the temporary designation S/2001 J 11. Aitne belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 million km and at an inclination of about 165°.
Aitne is about 3 kilometres in diameter, and orbits Jupiter at an average distance of 22,285,000 km in 712.04 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.
