Why is this a Ice World?Your planet orbits at 4.91 AU from its star, resulting in frigid temperatures of 113K.
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: 4.91 AU (>3 AU) or Temperature <200K✓ Temperature: 113K✓ Water content: 28.9% 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
rotation30
Very slow rotation - severe temperature swings between eternal day and night sides
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection
