Barren

None 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: 0.3x EarthTemperature: 292K
Habitability ScoreExtremely Harsh
25
Contributing Factors
water51
Good water content with liquid potential (low gravity lets water escape to space)
geology30
Geologically dead - no nutrient recycling
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere50
CO₂ atmosphere with moderate greenhouse effect
temperature100
Optimal temperature range for liquid water and life
magnetic Field30
No magnetic field - vulnerable to solar radiation — but the pulsar's beams bathe this orbit in hard X-rays

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.
