Magnetic FieldModerate Activity
Why is this a Ice Giant?Your planet has moderate mass (7.7x 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.

Surface Characteristics
Icy mantle surrounding rocky core, with hydrogen-helium atmosphereMoonsLife may exist on a moon
Moon 1rings0.010% - 1.6 radii
Inside the Roche limit (1.92 planet radii): torn apart into a ring system.
Moon 2recedingOcean world - life0.052% - 5.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 51/100).
