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

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).
