Carme is a retrograde non-spherical moon of Jupiter. It was found by Seth Barnes Nicholson at Mount Wilson Observatory in California in July 1938.^[1] It is named after the mythological Carme, mother by Zeus of Britomartis, a Cretan goddess.

Carme did not get its present name until 1975;^[3] before then, it was simply known as Jupiter XI. It was sometimes called "Pan"^[4] between 1955 and 1975. Note that Pan is now the name of a moon of Saturn.

It gives its name to the Carme group, made up of non-spherical retrograde moons orbiting Jupiter at a distance ranging between 23,000,000 and 24,000,000 km and at an inclination of about 165°. Its orbital elements are as of January 2000.^[2] They are changing a lot due to Solar and planetary perturbations.
