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.

Famous quotes containing the word group:
“No other group in America has so had their identity socialized out of existence as have black women.... When black people are talked about the focus tends to be on black men; and when women are talked about the focus tends to be on white women.”
—bell hooks (b. c. 1955)
