Class C Planets - Glacial Planet

Class C planets have extremely thin Oxygen- Nitrogen atmospheres. Specific gravity from 0.5 to 1.7 Earth normal. Meteorologically unstable causing violent conditions. Temps range from -10 to -190 degrees Celsius. Full life support necessary for colonization and death rates are high. No workable soil base so hydroponics-type Organics are limited. Modest mineral and chemicals exist so production of Ore and Equipment will be below average to none. Class C planets NOT recommended for colonization as their violent condition make it extremely hazardous. Some Class C planets have been adopted by the Federation and used as prison colonies with very effective results.
