Untitled Lava World

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: 0.68 AU, 268K equilibrium

Limited water content
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)
temperature0
Challenging but potentially habitable temperature (large moon stabilizes the axial tilt - steady seasons) (runaway tidal heating keeps the surface molten regardless of orbit)

Surface Characteristics

Runaway tidal heating keeps the surface molten - volcanic activity everywhere
Moons
Moon 1rings0.68% - 2.8 radii

Inside the Roche limit (2.80 planet radii): torn apart into a ring system.

Moon 2receding0.10% - 17.2 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 3merged0.10% - 8.6 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 4merged0.10% - 12.5 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 5merged0.10% - 9.1 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 6merged0.10% - 7.4 radii

Merged with an adjacent moon: too close for both to hold a stable orbit.

Moon 7receding0.10% - 11.3 radii
