Why is this a Ice Giant?Your planet has moderate mass (63.0x 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.
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
geology40
Extreme volcanic activity may be hazardous
rotation30
Very slow rotation - severe temperature swings between eternal day and night sides
Organic Chemistry29
Carbon and hydrogen present - organic chemistry possible - chlorine-laced environment attacks organic molecules (tidal pools cycle wet and dry - a boost for prebiotic chemistry) — but the ground itself is radioactive, and no magnetic field shields a world from its own crust
atmosphere18
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
temperature20
Very cold - water frozen, challenging for life
magnetic Field100
Magnetic field provides radiation protection
