{{Short description|Group of retrograde irregular satellites of Jupiter}}[[Image:TheIrregulars JUPITER GROUPS.svg|thumb|300px|This diagram illustrates the largest irregular satellites of Jupiter. The location of the Ananke group is illustrated by Ananke's presence near the bottom. An object's position on the horizontal axis indicates its distance from Jupiter. The vertical axis indicates its [[orbital inclination|inclination]]. [[Orbital eccentricity|Eccentricity]] is indicated by yellow bars illustrating the object's maximum and minimum distances from Jupiter. Circles illustrate an object's size in comparison to the others.]]

The '''Ananke group''' is a group of [[Retrograde motion|retrograde]] [[irregular satellite]]s of [[Jupiter]] that follow similar [[orbit]]s to [[Ananke (moon)|Ananke]] and are thought to have a common origin.

Their [[semi-major axis|semi-major axes]] (distances from Jupiter) range between 19.2 and 21.8 [[gigametre|Gm]], their [[orbital inclination]]s between 144.3° and 155.5°, and their [[Orbital eccentricity|orbital eccentricities]] between 0.09 and 0.30.

The members of the Ananke group are:<ref name="SheppardJewittPorco2004">{{Cite book |last1=Jewitt |first1=David C. |url=http://www.ifa.hawaii.edu/~jewitt/papers/JUPITER/JSP.2003.pdf |title=Jupiter.
