Magnetic Field Extreme Activity
Why is this a Ice Giant? Your planet has moderate mass (22.0x 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.

Surface Characteristics No solid surface - a deep volatile envelope over a supercritical water mantle and hot-ice interior Moons
Moon 1 receding Ocean world 0.056% - 11.7 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (7/100).
Moon 2 receding 0.10% - 21.6 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 3 receding 0.18% - 47.0 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
