Barren

Extreme Activity
Why is this a Barren?Your planet has an unusual composition that doesn't fit standard classifications, or lacks the elements needed for complex geological processes.
Barren worlds can form from uncommon element combinations or may be remnants of larger bodies that lost their atmospheres and volatile materials.
Classification Criteria:
Composition doesn't match standard planet typesMass: 5.6x EarthTemperature: 379K

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 Chemistry0
Limited organic chemistry potential - chlorine-laced environment attacks organic molecules
atmosphere4
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation)
temperature40
Extreme temperature - very difficult for life
magnetic Field30
No magnetic field - vulnerable to solar radiation — but the remnant's shock fronts flood this orbit with cosmic rays

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.
