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
water50
Limited water content
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)
temperature15
Frozen world - minimal potential for complex life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection (a large close moon may help stir the core dynamo (speculative))

Surface Characteristics
No solid surface - thick gaseous envelope with possible rocky core deep withinMoonsLife may exist on a moon
Moon 1recedingOcean world - life0.36% - 10.4 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, 92/100).
Moon 2merged0.39% - 11.3 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3rings0.052% - 1.8 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 4merged0.48% - 11.7 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
