Cozmo

Cozmo presents as glacial blue, with cryo-volcanic vents releasing frozen plumes. Surface temperatures range from -250 to -100°C at 1.1 atm, with sublimation plumes rising into the thin upper atmosphere. At 6,274 km across, the surface material is primarily methane clathrate and water-ice composites. Moonless. Any tidal effects are driven solely by the parent star, producing a simpler but still measurable geological response.
