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: 150.00 AU, 2200K equilibrium

Contributing Factors
water50
Water present but likely as steam
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
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 Field100
Magnetic field provides radiation protection (a large close moon may help stir the core dynamo (speculative))

Moons
Moon 1rings1.4% - 1.6 radii

Inside the Roche limit (1.79 planet radii): torn apart into a ring system.

Moon 2merged10% - 19.2 radii

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

Moon 3receding3.2% - 6.0 radii

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.
