Min 1c is the third moon from the rogue planet Min I in the unclaimed Min system. The smallest of the four moons, it has a thin atmosphere of nitrogen and carbon dioxide, and is composed of rocky material and water ices. Like its neighbors, Min 1c experiences tidal heating, though at a low enough level that its tectonic activity is relatively infrequent. In the past, it once had many active volcanoes, enough to possibly have supported an atmosphere that allowed the existence of liquid water. There is a sprawling cavern network beneath its surface.
