Carme

Carme, also known as Jupiter XI, is a retrograde irregular-shaped satellite belonging to the planet of Jupiter. This satellite was discovered by Seth Barnes Nicholson on July 30, 1938 at the Mount Wilson Observatory. It is part of the Carme group, with it being its group's largest satellite. There are sixteen other satellites in this group (grouped from largest to smallest):

All names end with "e", due to them being retrograde. This rule was established by the International Astronomical Union (IAU).

Formation
The formation of Carme is believed to be a stray asteroid from the neighboring Asteroid belt that was pulled in by Jupiter's gravitational pull. It is believed that is was pushed into deep space by other asteroids, and was pulled in by Jupiter's strong gravitational pull, yet had to be pretty close to Jupiter because of its composition. It is believed to be carbonaceous, the type of asteroids that make up the outer region of the Asteroid belt.

Surface
The surface of Carme is brown, which means it shows traces of carbon, proving it is a carbonaceous asteroid. Yet, if this is true, then this means that the other moons belonging to this group are responsible for Carme being in orbit around Jupiter or a majority of them are from the same region since they have a similar orbit.
