Class Q - Variable
Age: 2-10 billion years
Diameter: 4,000 - 15,000 km
Location: Hot, Ecosphere, and Cold Zones
Surface: Ranges from molten to water and/or carbon dioxide ice, due to eccentric orbit or variable output of star
Atmosphere: Ranges from tenuous to very dense
Examples: Genesis Planet
Class Q planets are found in all of the star's zones. Generally a bit smaller than Earth, they range in size from 4,000 to 15,00 kilometers in diameter. Due to the eccentric orbit and variable output of star, the surface can range from molten to water or ice. The atmosphere is tenuous to dense, and sustains no known life forms.
The Genesis planet began as Class M, but degenerated into Class Q due to unstable protomatter used in the creation process.
