Desert World

Low Activity
Why is this a Desert World?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: 0.4x EarthTemperature: 458K

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology60
Some geological activity provides slow nutrient cycling
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
Organic Chemistry20
Limited organic chemistry potential
atmosphere70
Nitrogen atmosphere provides protection but not breathable
temperature15
Extremely hot - hostile to known life forms
magnetic Field30
No magnetic field - vulnerable to solar radiation

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.
