Ice Giant
Magnetic FieldModerate Activity
Why is this a Ice Giant?Your planet has moderate mass (17.0x 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.
Classification Criteria:
✓ Mass: 17.0x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition
Habitability ScoreUninhabitable
Contributing Factors
water60
Water present but mostly frozen
geology90
Active geology recycles nutrients and drives carbon cycle
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)
temperature10
Frozen world - minimal potential for complex life
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings0.028% - 1.8 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2stableOcean world0.010% - 6.8 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 (7/100).
Moon 3stable0.016% - 11.0 radii
Small and distant: a quiet, stable companion.
Moon 4stable0.028% - 21.1 radii
Small and distant: a quiet, stable companion.
Moon 5receding0.12% - 31.5 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 6receding0.098% - 100.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
