Magnetic Field Extreme Activity
Why is this a Carbon World? Your planet's carbon (52.3%) outweighs its oxygen (0.0%), so the mineralogy flips from silicate rock to carbide - a graphite crust over a diamond mantle. Carbon worlds form in carbon-rich disks where there isn't enough oxygen to bind it all into silicates. Instead carbon condenses directly into graphite, carbides, and - under pressure at depth - diamond. They form water-poor, so no life takes hold.
✓ Carbon: 52.3% (>=20% required) ✓ Carbon exceeds Oxygen: 52.3% > 0.0% ✓ Mass: 6.9x Earth (<=8x hycean ceiling)
Habitability Score Uninhabitable
Contributing Factors water 0
No water - the recipe has no hydrogen and oxygen to form it (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 50
Carbon and hydrogen present - organic chemistry possible atmosphere 4
Atmosphere present but composition not ideal for life (severely compromised by extreme rotation) temperature 40
Extreme temperature - very difficult for life magnetic Field 100
