Rocky Terrestrial

Moderate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (44.1%) and iron (14.7%) 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: 44.1% + Iron: 14.7% + Magnesium: 14.7%✓ Mass: 1.0x Earth (terrestrial range)
Habitability ScoreUninhabitable

Contributing Factors
water0
No water - the recipe has no hydrogen and oxygen to form it
geology90
Active geology recycles nutrients and drives carbon cycle
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry20
Limited organic chemistry potential
atmosphere4
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation)
temperature70
Challenging but potentially habitable temperature
magnetic Field30
No magnetic field - vulnerable to solar radiation

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.
