One unnamed moon


Hydrogen, Helium, trace gasses


Calpamos[1][2] is the fourth planet in the Zeta2 Reticuli system.[3] It is a ringed gas giant[3] with three moons, including LV-223 and Acheron (LV-426).


Calapamos is a gas giant located within or around the habitable zone of one of the stars in the Zeta Reticuli system. It possesses rings, much like the planet Saturn; these rings are thought to be the remains of a disintegrated moon that was broken apart by the gravitational shift induced when Acheron (LV-426) was captured by Calpamos' orbit, some 40 million years ago.[4] The planet's coloration is somewhat mixed, in some parts light brown and in others a darker brown. Its most notable feature is its three small moons, including Acheron, where a derelict Engineer ship was located, and LV-223, which was the site of a major Engineer facility.


Not much is known about the materials or gases that make up the atmosphere of Calpamos (but is believed to have similar types of materials to the planet Jupiter).[citation needed]
