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: 17.0x EarthTemperature: 335K

Contributing Factors
water100
Abundant liquid water at surface temperature
geology40
Extreme volcanic activity may be hazardous
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 Field100
Magnetic field provides radiation protection — but the black hole's accretion disk bathes this orbit in hard X-ray radiation
