Surface. Endless dune seas and wind-carved rock under a permanent dust haze - scorching days, freezing nights
Desert World
✦ Radarada
Your planet is a hot (322K), bone-dry silicate rock that kept its atmosphere - with no water cycle to wash the air, wind lofts a permanent dust veil over endless dune seas.Magnetic FieldHigh Activity
Desert worlds are the Tatooine/Arrakis archetype: enough rock to build a solid surface, enough air to carry dust, and too little hydrogen for oceans or rain. Heat bakes out any trace moisture, so nothing interrupts the wind's work - dune seas, wind-carved rock, scorching days.
Classification Criteria:
✓ Hydrogen: 0.0% (<5% - bone dry, no water cycle)✓ Temperature: 322K (300-500K hot band)✓ Silicon + Iron + Magnesium: 50.0% (>=30% - a real rocky surface)✓ Holds an atmosphere to carry the dust haze
Habitability ScoreUninhabitable
Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry20
Limited organic chemistry potential
atmosphere70
Thin, dusty CO₂-nitrogen atmosphere - permanent haze of wind-borne sand
Nitrogen atmosphere provides protection but not breathabletemperature77
Warm - livable, but heat stress grows with every degree (extreme seasons: at 58° the poles swing between months-long day and night: −7% habitability)
magnetic Field100
Magnetic field provides radiation protection
