In the NoLWoCS system this would probably be a Chthonian type world, which has lost any volatiles it once may have had. There still could be a vaporous atmosphere on such a world, since several normally solid elements would be near or above their melting or boiling point.
This planet has a mass of about 1.3 Earths, so would have higher gravity than our planet - that means any atmosphere that does form will last longer, despite the temperature. |
