Min 1b is the second moon from the rogue planet Min I in the unclaimed Min system. Unique among known celestial bodies, Min 1b supports life in spite of a total lack of sunlight. The same tidal heating that makes Min 1a violently volcanically active causes geothermal activity on Min 1b, giving it enough internal heat to sustain a liquid water ocean. Additionally, its thick hydrogen atmosphere provides enough of a barrier to prevent too much warmth from escaping, allowing the surface of the ocean to be free from ice in many places. Min 1b is home to countless colonies of bioluminescent bacteria that cluster around hydrothermal vents at the bottom of the ocean, along with some bioluminescent plants. A community formed by researchers interested in studying Min 1b's environment, survivalists, and outlaws drawn to the system's unclaimed status formed in 2816.
