Gas Giant Magnetic Field Extreme Activity
Why is this a Gas Giant? Your planet has 0.0% hydrogen and helium, combined with a mass of 100.0x 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: 0.0% (>60% required) ✓ Mass: 100.0x Earth (>10x required)

Contributing Factors water 2
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans (water stripped by extreme rotation) geology 40
Extreme volcanic activity may be hazardous rotation 0
Catastrophic rotation - centrifugal forces would destroy surface structures and prevent atmosphere retention Organic Chemistry 0
Limited organic chemistry potential - chlorine-laced environment attacks organic molecules atmosphere 3
Hydrogen-rich atmosphere typical of gas giants (severely compromised by extreme rotation) temperature 0
Inferno world - temperatures exceed all possibility of life magnetic Field 100
