Lava World

Extreme Activity
Why is this a Lava World?Your planet's proximity to its star (0.10 AU) results in extreme surface temperatures of 879K.
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.

Contributing Factors
water50
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 Chemistry100
All CHNOPS elements present - building blocks of life
atmosphere16
Atmosphere present but composition not ideal for life (partially stripped by slow rotation)
temperature5
Scorching temperatures - surface likely molten, no chance for life
magnetic Field30
No magnetic field - vulnerable to solar radiation

Surface views from three worlds: rocky ground under a ringed sky, a cloud deck, and a lit desert

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.
