Why is this a Ice World?Your planet orbits at 4.78 AU from its star, resulting in frigid temperatures of 127K.
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: 4.78 AU (>3 AU) or Temperature <200K✓ Temperature: 127K✓ Water content: 25.0% for ice formation

Contributing Factors
water11
Limited water content - frozen solid, no liquid phase at this temperature
geology60
Some geological activity provides slow nutrient cycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry75
All CHNOPS elements present - building blocks of life - chlorine-laced environment attacks organic molecules — but the ground itself is radioactive, and no magnetic field shields a world from its own crust
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection
