Autonoe was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2001, and given the temporary designation S/2001 J 1.

[6][1][7] Autonoe is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 24,264,000 km in 719.01 days.

It orbits at an inclination of 151° to the ecliptic (150° to Jupiter's equator) in a retrograde direction and with an eccentricity of 0.369.

Autonoe was named in August 2003 after the Greek mythological figure Autonoë, conquest of Zeus (Jupiter),[8] mother of the Charites (Gracies), according to some authors.
