Rocky Terrestrial

Magnetic FieldLow Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (33.3%) and iron (0.0%) 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: 33.3% + Iron: 0.0% + Magnesium: 0.0%✓ Mass: 0.7x Earth (terrestrial range)
Habitability ScoreExtremely Harsh

Contributing Factors
water50
Water present but likely as steam (low gravity lets water escape to space)
geology60
Some geological activity provides slow nutrient cycling
rotation25
Very fast rotation - perpetual hurricane-force winds, extreme Coriolis effects, hazardous for complex life
Organic Chemistry50
Carbon and hydrogen present - organic chemistry possible
atmosphere35
Dense CO₂ atmosphere with extreme greenhouse effect
temperature15
Extremely hot - hostile to known life forms
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.
