Gas Giant

Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 87.0% hydrogen and helium, combined with a mass of 60.0x Earth, which exceeds the gas giant threshold.
Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.
Classification Criteria:
✓ Hydrogen + Helium: 87.0% (>60% required)✓ Mass: 60.0x Earth (>10x required)
Habitability ScoreExtremely Harsh

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 Chemistry80
Core organic elements (CHNO) present
atmosphere12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection

MoonsLife may exist on a moon
Moon 1recedingOcean world0.080% - 6.0 radii

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

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

A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (22/100).

Moon 2recedingOcean world - life0.10% - 9.5 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, 96/100).

Moon 3recedingOcean world0.10% - 14.5 radii

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

A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (7/100).

Moon 4receding0.10% - 27.2 radii

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

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.
