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: 278K
Habitability ScoreUninhabitable
12
Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
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 Chemistry20
Limited organic chemistry potential
atmosphere16
Atmosphere present but composition not ideal for life (partially stripped by slow rotation)
temperature100
Optimal temperature range for liquid water and 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
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 2stable0.010% - 60.7 radii
Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
Moon 3receding1.4% - 27.2 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
