ocr: Class H planets have extremely thin Oxygen/ Nitrogen atmospheres. Specific gravities are within 0.8 to 2.6 Earth normal. Climate patterns are violent with temperatures from 45 to 400 degrees Celcius. Full life support required for colonization. Zero workable soil and harsh conditions make Urganics pro- ction impossible. Good trace elements for equipment but conditions make production a gamble at best. Excellent Ore production possibilites as material is often ejected by volcanic activity and found on the surface. Very dangerous for colony growth as unstable planetary crusts often lead to the c ...
