Magnetic Field Extreme Activity
Why is this a Ice Giant? Your planet has moderate mass (27.0x Earth) with significant water, carbon, and nitrogen content, characteristic of ice giants. Ice giants like Uranus and Neptune have icy interiors with thick atmospheres of hydrogen and helium, but not enough to be classified as gas giants.
✓ Mass: 27.0x Earth (5-20x range) ✓ Water/Carbon/Nitrogen rich composition
Habitability Score Uninhabitable
Contributing Factors water 15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans geology 50
Extreme volcanic activity may be hazardous (tidal flexing sustains geologic activity) rotation 10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only Organic Chemistry 80
Core organic elements (CHNO) present atmosphere 12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation) temperature 15
Frozen world - minimal potential for complex life (large moon stabilizes the axial tilt - steady seasons) magnetic Field 100

Moon 1 rings 0.011% - 2.1 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2 receding Ocean world - life 0.13% - 7.6 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, 55/100).
Moon 3 stable 0.0016% - 19.2 radii
Small and distant: a quiet, stable companion.
Moon 4 receding 2.5% - 47.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
+5 temperature: large moon stabilizes the axial tilt - steady seasons +10 geology: tidal flexing sustains geologic activity
