Magnetic Field Moderate Activity
Why is this a Ice Giant? Your planet has moderate mass (12.0x 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: 12.0x 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 90
Active geology recycles nutrients and drives carbon cycle rotation 60
Fast rotation - strong global wind patterns and weather systems, but manageable Organic Chemistry 80
Core organic elements (CHNO) present atmosphere 30
Hydrogen-rich atmosphere typical of gas giants temperature 10
Frozen world - minimal potential for complex life magnetic Field 100

Surface Characteristics Icy mantle surrounding rocky core, with hydrogen-helium atmosphere Moons
Moon 1 rings 0.010% - 3.5 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2 receding 0.056% - 100.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 3 stable 0.00079% - 13.0 radii
Small and distant: a quiet, stable companion.
