Ice Giant
Magnetic FieldModerate Activity
Why is this a Ice Giant?Your planet has moderate mass (6.2x 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 oceansgeology90
Active geology recycles nutrients and drives carbon cyclerotation10
