Ice Giant

✦ Prismatopia
Magnetic FieldExtreme Activity
Why is this a Ice Giant?Your planet has moderate mass (210.0x Earth) with significant water, carbon, and nitrogen content, characteristic of ice giants.
Ice giants like Uranus and Neptune have icy interiors with thick atmospheres of hydrogen and helium, but not enough to be classified as gas giants.
Classification Criteria:
✓ Mass: 210.0x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition
Habitability ScoreUninhabitable

Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology50
Extreme volcanic activity may be hazardous (tidal flexing sustains geologic activity)
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry100
All CHNOPS elements present - building blocks of life (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature10
Frozen world - minimal potential for complex life
magnetic Field100
Magnetic field provides radiation protection

MoonsLife may exist on a moon
Moon 1recedingOcean world - life0.056% - 6.9 radii

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

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

Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 51/100).

Moon 2recedingOcean world - life0.10% - 9.9 radii

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

Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 91/100).

Moon 3rings0.079% - 3.2 radii

Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).

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.
