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: 5.8x EarthTemperature: 837K

Contributing Factors
water50
Limited water content
geology40
Extreme volcanic activity may be hazardous
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
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)
atmosphere70
Nitrogen atmosphere provides protection but not breathable
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 — but the black hole's accretion disk bathes this orbit in hard X-ray radiation
