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: 3.31 AU, 129K equilibrium

Contributing Factors
water60
Water present but mostly frozen
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
Very cold - water frozen, challenging for life (runaway tidal heating keeps the surface molten regardless of orbit)

Moons
Moon 1stable0.00030% - 4.0 radii

Small and distant: a quiet, stable companion.

Tidal braking locked the planet to its moon: one face forever moonward.

Moon 2receding0.00030% - 4.6 radii

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).

Moon 3merged0.071% - 5.3 radii

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

Moon 4stable0.00030% - 6.1 radii

Small and distant: a quiet, stable companion.

Moon 5stable0.00030% - 7.0 radii

Small and distant: a quiet, stable companion.

New: Stand on Your World 🏔️

Every planet you build can now be seen from the ground. The terrain, the color of the sky, the weather and what hangs overhead are all read from the same numbers that shape the globe — so a thin-aired world gives you sunlit rock under a near-black sky crowded with stars, a runaway greenhouse seals you under an unbroken sulfur lid, and a gas giant leaves you in the cloud tops with nothing solid beneath you at all. If one of your moons wandered inside the Roche limit, what is left of it arcs overhead as rings.
