Lava World

✦ Aresidon System
Extreme Activity
Why is this a Lava World?Your planet's proximity to its star (0.10 AU) results in extreme surface temperatures of 15633K.
Lava worlds orbit so close to their stars that rocky surfaces melt into oceans of molten rock. Recent planet formation can also create temporary lava worlds.
Classification Criteria:

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology40
Extreme volcanic activity may be hazardous
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry20
Limited organic chemistry potential
atmosphere10
No atmosphere - exposed to radiation and temperature extremes
temperature0
Inferno world - temperatures exceed all possibility of life
magnetic Field30
No magnetic field - vulnerable to solar radiation

Moons
Moon 1receding0.010% - 100.0 radii

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

Moon 2stable0.0016% - 84.5 radii

Small and distant: a quiet, stable companion.

Moon 3merged10% - 100.0 radii

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

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.
