Their semi-major axes (distances from Jupiter) range between 22,900,000 and 24,100,000 km, their inclinations between 164.9° and 165.5°, and their orbital eccentricities between 0.23 and 0.27 (with one exception).
- Carme (the biggest, which gives its name to the group)
- S/2003 J 5
- Kalyke (redder than the others)
- S/2003 J 9
- S/2003 J 10
The International Astronomical Union (IAU) reserves names in -e for all retrograde moons, including this group's members.
Origin[change | edit source]
The Carme group may once have been a single body that was broken apart by an impact. Further support to the single body origin comes from the known colours: all the moons appear light red, and infrared spectra, similar to D-type asteroids.
