Why is this a Barren?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: 1.0x EarthTemperature: 950K
Habitability ScoreUninhabitable

Contributing Factors
water20
Very dry - minimal water
geology90
Active geology recycles nutrients and drives carbon cycle
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry79
All CHNOPS elements present - building blocks of life - chlorine-laced environment attacks organic molecules (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature10
Scorching - hot enough to melt lead, though rock stays solid; no chance for life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection (a large close moon may help stir the core dynamo (speculative))

Surface Characteristics
Barren rocky surface with unusual elemental composition
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
