Gas Giant Magnetic Field Extreme Activity
Why is this a Gas Giant? Your planet has 60.2% hydrogen and helium, combined with a mass of 17.0x 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.

Moon 1 receding Ocean world - life 0.089% - 5.1 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, 84/100).
