Magnetic Field Moderate Activity
Why is this a Ice Giant? Your planet has moderate mass (16.0x 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: 16.0x 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 100
Active geology recycles nutrients and drives carbon cycle (tidal flexing sustains geologic activity) rotation 10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only Organic Chemistry 84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry) atmosphere 12
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation) temperature 0
Near absolute zero - all molecular activity ceases, impossible for life magnetic Field 100

Moon 1 rings 0.046% - 4.6 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2 stable Ocean world 0.046% - 6.1 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 (34/100).
Moon 3 stable 0.049% - 13.6 radii
Small and distant: a quiet, stable companion.
Moon 4 stable 0.035% - 29.3 radii
Small and distant: a quiet, stable companion.
