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 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)
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1stableOcean world0.0045% - 5.1 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 (11/100).
Moon 2stableOcean world0.0050% - 6.0 radii
Small and distant: a quiet, stable companion.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (4/100).
Moon 3receding0.063% - 15.8 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 4receding0.050% - 24.5 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
