Rocky Terrestrial

High Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (19.5%) and iron (13.0%) content, forming a rocky terrestrial body.
Rocky terrestrial planets are primarily composed of silicate rocks and metals. They're the most common type of small planet in the universe.
Classification Criteria:
✓ Silicon: 19.5% + Iron: 13.0% + Magnesium: 6.5%✓ Mass: 4.3x Earth (terrestrial range)

Contributing Factors
water20
Very dry - minimal water
geology90
Active geology recycles nutrients and drives carbon cycle
rotation30
Very slow rotation - severe temperature swings between eternal day and night sides
Organic Chemistry100
All CHNOPS elements present - building blocks of life
atmosphere30
CO₂ atmosphere with moderate greenhouse effect (partially stripped by slow rotation)
temperature20
Very cold - water frozen, challenging for life
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.
