No water - the recipe has no hydrogen and oxygen to form it
geology60
Some geological activity provides slow nutrient cycling
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry20
Limited organic chemistry potential
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature10
Frozen world - minimal potential for complex life
magnetic Field100
Magnetic field provides radiation protection
