Surface. Graphite plains and carbide ridges over a diamond mantle - a glittering coal-black world
Carbon World
✦ Te 0284
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.Destroyed — no longer habitableMagnetic FieldModerate Activity
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.
Classification Criteria:
✓ Carbon: 52.3% (>=20% required)✓ Carbon exceeds Oxygen: 52.3% > 0.0%✓ Mass: 1.8x Earth (<=8x hycean ceiling)
