The Ananke group is a group of retrograde irregular satellites of Jupiter that follow similar orbits to Ananke and are thought to have a common origin.
Their semi-major axes (distances from Jupiter) range between 19.3 and 22.7 Gm, their orbital inclinations between 145.7° and 154.8°, and their orbital eccentricities between 0.02 and 0.28.
The core members include (from largest to smallest):
- Ananke
- Praxidike
- Iocaste
- Harpalyke
- Thyone
- Euanthe
- Euporie
The International Astronomical Union (IAU) reserves names ending in -e for all retrograde moons, including this group's members.
