Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.
Classification Criteria:
Composition doesn't match standard planet typesMass: 0.5x EarthTemperature: 696K
Habitability ScoreUninhabitable
5
Contributing Factors
water15
Abundant water - boiling away, little would be retained
geology60
Some geological activity provides slow nutrient cycling
rotation30
Very slow rotation - extreme temperature swings between eternal day and night sides
Organic Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere21
Dense CO₂ atmosphere with extreme greenhouse effect (partially stripped by slow rotation)
temperature5
Scorching - hot enough to melt lead, though rock stays solid; no chance for life (extreme seasons: at 123° the poles swing between months-long day and night: −6% habitability)
magnetic Field30
No magnetic field - vulnerable to solar radiation
