Ananke group

The Ananke group is made up of moons of Jupiter which share similar orbits. Their semi-major axes range between 19.3 and 22.7 Gm, their inclinations between 145.7° and 154.8°, and their eccentricities between 0.02 and 0.28.

The group numbers between eight and sixteen members, depending on how rigorous the definition is. The eight core members are (in order of increasing distance from Jupiter):

S/2003 J 16
S/2003 J 21
Euanthe
Harpalyke
Praxidike
Thyone
Ananke, the largest, which gives its name to the group
Iocaste

The eight fringe members of the group are:

The International Astronomical Union (IAU) reserves names in -e for these moons.
