Min I

Min I is a gas giant dominated by ammonia clouds. Unattached to any known star it is drifting through space and pulling four orbiting moons along with it.

Min I is of Jupiter-mass and generates its own heat via the Kelvin Helmholtz Mechanism. What this means is that as the surface of the planet cools, the pressure on the planet drops and the surface shrinks, which in turn heats the core of the planet (600K range).

Min 1a
An uninhabited, rocky moon that was strip-mined long ago. It is unknown whether this moon formed from the accretion disk that created Min I or was "picked up" along the rogue planet's journey through space.

Min 1b
Min 1b is the largest moon orbiting the rogue gas giant. It has a thin atmosphere and is surprisingly warm because of the thermal heating produced by its eccentric orbit around Min I. The moon even has bioluminescent bacteria living near hydrothermal vents at the bottom of its vast oceans. Over the years a small encampment of settlers has set up residence here.

Despite not being ideal for human habitation, a couple of settlements have been built. These are at risk due to an ongoing debate as to whether Min 1b should be placed under the Fair Chance Act. Cynics say the reason it hasn't happened is that there aren't any valuable resources here, since the entire system was strip mined a long time ago. Scientists on Min 1b nevertheless are engaged in researching the native bioluminescent bacteria.

Min 1c
The smallest moon in orbit around Min I. It lacks both an atmosphere and resources.

Min 1d
A rocky moon whose landscape is dotted with impact craters.

Of potential interest in researching the geological history of the system.
