Lava World
Magnetic FieldExtreme Activity
Why is this a Lava World?Runaway tidal heating from its moons keeps the surface molten - the planet is kneaded like Io, only far harder.
Resonant, close-in moons pump orbital eccentricity, and the resulting tidal flexing dissipates enormous heat in the interior. Past a threshold the crust cannot cool: volcanism resurfaces the world continuously.
Classification Criteria:
✓ Close-in moons in a resonant configuration✓ Tidal heat flux beyond the runaway threshold- Orbit itself was fine: 0.83 AU, 305K equilibrium

Contributing Factors
water90
Good water content with liquid potential
geology40
Extreme volcanic activity may be hazardous
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere16
Atmosphere present but composition not ideal for life (partially stripped by slow rotation)
temperature15
Optimal temperature range for liquid water and life (runaway tidal heating keeps the surface molten regardless of orbit)
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1receding0.10% - 4.6 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Moon 2merged0.10% - 4.8 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3receding0.10% - 12.7 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 4receding0.10% - 33.7 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
