No water - the recipe has no hydrogen and oxygen to form it
geology30
Geologically dead - no nutrient recycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry20
Limited organic chemistry potential
atmosphere50
CO₂ atmosphere with moderate greenhouse effect
temperature100
Optimal temperature range for liquid water and life
magnetic Field30
No magnetic field - vulnerable to solar radiation — but the pulsar's beams bathe this orbit in hard X-rays
