Magnetic Field Extreme Activity
Why is this a Gas Giant? Your planet has 94.7% hydrogen and helium, combined with a mass of 109.0x Earth, which exceeds the gas giant threshold. Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.

Surface Characteristics No solid surface - thick gaseous envelope with possible rocky core deep within Moons Life may exist on a moon
Moon 1 rings 0.00014% - 1.8 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2 stable Ocean world 0.018% - 7.1 radii
Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (15/100).
Moon 3 receding Ocean world - life 0.40% - 15.4 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, 74/100).
