. 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 Carme group is a group of retrograde irregular satellites of Jupiter that follow similar to Carme and are thought to have a common origin.
Their semi-major axis (distances from Jupiter) range between 22.7 and 23.6 gigametre, their orbital inclinations between 164.4° and 164.9°, and their orbital eccentricities between 0.25 and 0.28 (with one exception).

The International Astronomical Union (IAU) reserves names ending in -e for all retrograde moons.
Further support to the single body origin comes from the known colours: all the satellites appear light red, with color index B-V= 0.76 and V-R= 0.47 and infrared spectra, similar to . These data are consistent with a progenitor from the Hilda family or a Jupiter trojan.
