Magnetic Field Extreme Activity
Why is this a Gas Giant? Your planet has 15.1% hydrogen and helium, combined with a mass of 48.0x 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: 15.1% (>60% required) ✓ Mass: 48.0x Earth (>10x required)
