Why is this a Ice World?Your planet orbits at 4.00 AU from its star, resulting in frigid temperatures of 145K.
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: 4.00 AU (>3 AU) or Temperature <200K✓ Temperature: 145K✓ Water content: 44.2% for ice formation
Habitability ScoreExtremely Harsh
Contributing Factors
water34
Water present but mostly frozen (low gravity lets water escape to space)
geology30
Geologically dead - no nutrient recycling
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature20
Very cold - water frozen, challenging for life
magnetic Field30
No magnetic field - vulnerable to solar radiation
