Lava World

Extreme 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: 0.70 AU, 5909K equilibrium

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology40
Extreme volcanic activity may be hazardous
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere4
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation)
temperature0
Inferno world - temperatures exceed all possibility of life (large moon stabilizes the axial tilt - steady seasons) (runaway tidal heating keeps the surface molten regardless of orbit)
magnetic Field35
No magnetic field - vulnerable to solar radiation (a large close moon may help stir the core dynamo (speculative))

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

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

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.
