Magnetic Field Extreme Activity
Why is this a Ice Giant? Your planet has moderate mass (325.0x 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.

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 100
All CHNOPS elements present - building blocks of life 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

Surface Characteristics No solid surface - a deep volatile envelope over a supercritical water mantle and hot-ice interior Moons Life may exist on a moon
Moon 1 stable Ocean world 0.035% - 5.4 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 (21/100).
Moon 2 receding Ocean world - life 0.056% - 6.9 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 51/100).
Moon 3 receding Ocean world - life 0.10% - 9.9 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 91/100).
Moon 4 receding 0.074% - 50.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 5 rings 0.079% - 3.2 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
