Class A planets are very small, barren worlds rife with volcanic activity. This

activity traps carbon dioxide in the atmosphere and keeps temperatures on Class A planets very hot, no matter the location in a star system. When the volcanic activity ceases, the planet "dies" and is then considered a Class C - Geoinactive planet.
