Space is a harsh place, and humans are delicate creatures. The first step toward habitability is achieving a stable, survivable temperature. This is measured in millikelvins, or 1/1000 of a degree kelvin. By this scale 273,000 mK is freezing and 373,000 mK is boiling, and Earth has an average temperature of 287,000 mK.
Terraforming[edit | edit source]
At temperatures below freezing, any existing water will transfer to "Frozen in Ice". Above freezing, ice will melt into water and raise the sea level.
At temperatures above the boiling point, water will evaporate to being "Retained by Atmosphere". If temperatures drop below boiling, water vapor will precipitate and raise the sea level.
Habitability for plants and microbes to grow on a planets surface requires a global temperature of 200,000 to 374,000 mK. Habitability for animals and humans outside of a Hab building is a narrower range between the freezing and boiling points of 237,000 to 337,000 mK.
Heating a world to above 1,500,000mK will create lava oceans.
