Gas Giant Magnetic Field Extreme Activity
Why is this a Gas Giant? Your planet has 60.7% 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.
✓ Hydrogen + Helium: 60.7% (>60% required) ✓ Mass: 17.0x Earth (>10x required)

Moon 1 stable Ocean world 0.010% - 6.1 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 (14/100).
Moon 2 stable 0.018% - 10.4 radii
Small and distant: a quiet, stable companion.
Moon 3 stable 0.020% - 15.4 radii
Small and distant: a quiet, stable companion.
Moon 4 stable 0.035% - 100.0 radii
Small and distant: a quiet, stable companion.
Moon 5 receding 0.063% - 26.1 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 6 rings 0.10% - 1.5 radii
Inside the Roche limit (1.79 planet radii): torn apart into a ring system.
