Water exists only in the ice. The steep mountains are connected by underground tunnels and huge caverns, studded with sparkling minerals. There is neither dry land nor seas on this marshy planet. Rather, the sticky surface resembles melted marshmallow. Temperatures are warm.
Rain is plentiful, but is immediately absorbed into the surface before it can collect in a pool.
A nearby moon keeps the Bog Planet in deep shadows for most of the day which lasts for 52 hours. Thousands of active volcanoes continually spew lava which means that the molten surface of Magma Planet constantly reshapes itself. The planet's magnetic field is particularly strong at the peaks of the highest mountains. An abundance of rare gases color the dense atmosphere a deep orange-red color. This planet does not rotate so it is always day on one side and eternally night on the other.
