Magnetic FieldModerate Activity
Why is this a Ice Giant?Your planet has moderate mass (6.0x 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.
