Ice World

✦ Gresmond
Magnetic FieldLow Activity
Why is this a Ice World?Your planet orbits at 92.50 AU from its star, resulting in frigid temperatures of 138K.
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: 92.50 AU (>3 AU) or Temperature <200K✓ Temperature: 138K✓ Water content: 44.1% 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 Chemistry84
Core organic elements (CHNO) present (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

New: Stand on Your World 🏔️

Every planet you build can now be seen from the ground. The terrain, the color of the sky, the weather and what hangs overhead are all read from the same numbers that shape the globe — so a thin-aired world gives you sunlit rock under a near-black sky crowded with stars, a runaway greenhouse seals you under an unbroken sulfur lid, and a gas giant leaves you in the cloud tops with nothing solid beneath you at all. If one of your moons wandered inside the Roche limit, what is left of it arcs overhead as rings.
