No life — too cold for liquid waterMagnetic FieldLow Activity
Why is this a Ice World?Your planet orbits at 2.57 AU from its star, resulting in frigid temperatures of 140K.
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: 2.57 AU (>3 AU) or Temperature <200K✓ Temperature: 140K✓ Water content: 29.9% for ice formation

Contributing Factors
water60
Water present but mostly frozen
geology60
Some geological activity provides slow nutrient cycling
rotation30
Very slow rotation - severe temperature swings between eternal day and night sides
Organic Chemistry100
All CHNOPS elements present - building blocks of life (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere42
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection
