Gas Giant

✦ Camislia System
Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 63.7% hydrogen and helium, combined with a mass of 18.0x 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: 63.7% (>60% required)✓ Mass: 18.0x Earth (>10x required)

Contributing Factors
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology40
Extreme volcanic activity may be hazardous
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry84
Core organic elements (CHNO) present (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 1rings0.010% - 1.8 radii

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

Moon 2stable0.00020% - 5.4 radii

Small and distant: a quiet, stable companion.

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

Moon 3stable0.016% - 18.3 radii

Small and distant: a quiet, stable companion.

Moon 4stable0.00063% - 100.0 radii

Small and distant: a quiet, stable companion.

Moon 5stable0.00050% - 33.6 radii

Small and distant: a quiet, stable companion.

Moon 6rings0.010% - 2.7 radii

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

Moon 7rings0.00079% - 1.5 radii

Inside the Roche limit (1.79 planet radii): torn apart into a ring system.

Moon 8recedingOcean world - life0.089% - 9.7 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, 76/100).

Moon 9stable0.010% - 51.2 radii

Small and distant: a quiet, stable companion.

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.
