Rocky Terrestrial

Magnetic FieldHigh Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (25.6%) and iron (20.9%) 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: 25.6% + Iron: 20.9% + Magnesium: 14.0%✓ Mass: 3.5x Earth (terrestrial range)

Contributing Factors
water20
Very dry - minimal water
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
Organic Chemistry20
Limited organic chemistry potential
atmosphere100
Nitrogen-oxygen atmosphere - breathable and protective
temperature40
Extreme temperature - very difficult for life
magnetic Field100
Magnetic field provides radiation protection

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.
