Why is this a Ice World?Your planet orbits at 27.00 AU from its star, resulting in frigid temperatures of 239K.
Ice worlds form beyond the frost line where temperatures are low enough for water and other volatiles to freeze solid. They may have subsurface oceans beneath thick ice shells.
Classification Criteria:
✓ Distance: 27.00 AU (>3 AU) or Temperature <200K✓ Temperature: 239K✓ Water content: 44.9% for ice formation

Contributing Factors
water60
Water present but mostly frozen
geology60
Some geological activity provides slow nutrient cycling
rotation60
Fast rotation - strong global wind patterns and weather systems, but manageable
Organic Chemistry20
Limited organic chemistry potential
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature40
Extreme temperature - very difficult for life
magnetic Field100
Magnetic field provides radiation protection — but the black hole's accretion disk bathes this orbit in hard X-ray radiation
