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

Contributing Factors
water60
Water present but mostly frozen
geology100
Active geology recycles nutrients and drives carbon cycle (tidal flexing sustains geologic activity)
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry100
All CHNOPS elements present - building blocks of life
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

MoonsLife may exist on a moon
Moon 1rings0.020% - 3.3 radii

Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).

Moon 2stableOcean world0.043% - 4.9 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 (9/100).

Moon 3recedingOcean world - life0.10% - 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, 45/100).

Moon 4recedingOcean world - life0.19% - 13.9 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, 48/100).

Moon 5recedingOcean world0.45% - 22.5 radii

A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (5/100).
