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
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 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)
temperature20
Very cold - water frozen, challenging for life
magnetic Field100

MoonsLife may exist on a moon
Moon 1recedingOcean world - life0.12% - 8.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 76/100).
