Calpamos is a ringed gas giant which is the fifth planet from the star Zeta 2 in Zeta Reticuli.
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).
Calpamos has a ring like the planet Saturn but smaller (possibly from a small moon that may have been destroyed by a collision with an asteroid or simply are the remains of the original formation of the planet). Its coloration has a somewhat mixed, in some parts is light brown and in others a darker brown. Its most notable feature is its three small moons, including Acheron, where the Derelict landed.
