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: 253K
Habitability ScoreUninhabitable
12
Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology90
Active geology recycles nutrients and drives carbon cycle
rotation30
Very slow rotation - severe temperature swings between eternal day and night sides
Organic Chemistry20
Limited organic chemistry potential
atmosphere24
Atmosphere present but composition not ideal for life (partially stripped by slow rotation)
temperature70
Challenging but potentially habitable temperature
magnetic Field100
Magnetic field provides radiation protection

Moons
Moon 1rings0.028% - 2.8 radii

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

Moon 2rings0.010% - 4.3 radii

Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).

Moon 3stable0.010% - 7.5 radii

Small and distant: a quiet, stable companion.

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.
