Ice World

Magnetic FieldLow Activity
Why is this a Ice World?Your planet orbits at 3.49 AU from its star, resulting in frigid temperatures of 160K.
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: 3.49 AU (>3 AU) or Temperature <200K✓ Temperature: 160K✓ Water content: 44.1% for ice formation

Contributing Factors
water60
Water present but mostly frozen
geology60
Some geological activity provides slow nutrient cycling
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere28
Nitrogen atmosphere provides protection but not breathable (partially stripped by slow rotation)
temperature25
Very cold - water frozen, challenging for life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1receding0.63% - 12.0 radii

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).

Tidal braking locked the planet to its moon: one face forever moonward.

Moon 2merged0.10% - 19.0 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.
