Gas Giant
Magnetic 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 ScoreExtremely Harsh
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)
temperature15
Frozen world - minimal potential for complex life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1merged1.0% - 100.0 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 2stable0.010% - 11.0 radii
Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
Moon 3receding0.022% - 51.1 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 4merged0.32% - 22.0 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 5receding0.10% - 81.1 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 6merged0.20% - 54.4 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 7recedingOcean world0.22% - 20.3 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (25/100).
