Ice Giant Magnetic Field Extreme Activity
Why is this a Ice Giant? Your planet has moderate mass (188.0x 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 geology 40
Extreme volcanic activity may be hazardous rotation 10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only Organic Chemistry 20

Surface Characteristics No solid surface - a deep volatile envelope over a supercritical water mantle and hot-ice interior Moons Life may exist on a moon
Moon 1 receding 0.071% - 19.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Moon 2 receding Ocean world - life 0.063% - 8.6 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 58/100).
