Why is this a Ice World?Your planet orbits at 1052.50 AU from its star, resulting in frigid temperatures of 9K.
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: 1052.50 AU (>3 AU) or Temperature <200K✓ Temperature: 9K✓ Water content: 44.1% for ice formation

Contributing Factors
water34
Water present but mostly frozen (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 Chemistry80
Core organic elements (CHNO) present
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature0
Near absolute zero - all molecular activity ceases, impossible for life
magnetic Field30
No magnetic field - vulnerable to solar radiation

Surface views from three worlds: rocky ground under a ringed sky, a cloud deck, and a lit desert

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.
