Why is this a Desert World?Your planet is a hot (345K), 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.
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: 3.6% (<5% - bone dry, no water cycle)✓ Temperature: 345K (300-500K hot band)✓ Silicon + Iron + Magnesium: 55.4% (>=30% - a real rocky surface)✓ Holds an atmosphere to carry the dust haze

Contributing Factors
water20
Very dry - minimal water
geology60
Some geological activity provides slow nutrient cycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature70
Challenging but potentially habitable temperature
magnetic Field30
No magnetic field - vulnerable to solar radiation
