Why is this a Ice World?Your planet orbits at 1.21 AU from its star, resulting in frigid temperatures of 204K.
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: 1.21 AU (>3 AU) or Temperature <200K✓ Temperature: 204K✓ Water content: 30.8% for ice formation
Habitability ScoreExtremely Harsh

Contributing Factors
water26
Good water content - frozen solid, no liquid phase at this temperature (low gravity lets water escape to space)
geology30
Geologically dead - no nutrient recycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry100
All CHNOPS elements present - building blocks of life
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature40
Extreme temperature - very difficult for life
magnetic Field30
No magnetic field - vulnerable to solar radiation
