Barren

Magnetic FieldModerate 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: 1.0x EarthTemperature: 310K

Contributing Factors
water50
Limited water content
geology90
Active geology recycles nutrients and drives carbon cycle
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry54
Carbon and hydrogen present - organic chemistry possible (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere20
CO₂ atmosphere with moderate greenhouse effect (partially stripped by slow rotation)
temperature100
Optimal temperature range for liquid water and life (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection (a large close moon may help stir the core dynamo (speculative))

Inside the Roche limit (2.80 planet radii): torn apart into a ring system.

Moon 2receding1.1% - 26.1 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.
