Gas Giant
✦ Solar SystemMagnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 86.0% hydrogen and helium, combined with a mass of 10.1x 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: 86.0% (>60% required)✓ Mass: 10.1x Earth (>10x required)
Habitability ScoreUninhabitable
Contributing Factors
water60
Water present but mostly frozen
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)
temperature10
Frozen world - minimal potential for complex life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings0.069% - 2.5 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2stableOcean world0.017% - 3.9 radii
Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (7/100).
Moon 3stableOcean world0.019% - 6.9 radii
Small and distant: a quiet, stable companion.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (18/100).
Moon 4stable0.030% - 15.4 radii
Small and distant: a quiet, stable companion.
Moon 5stable0.046% - 19.9 radii
Small and distant: a quiet, stable companion.
Moon 6receding0.052% - 29.6 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 7receding0.14% - 55.5 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
