Venus Like

Magnetic FieldModerate Activity
Why is this a Venus Like?Your planet has a thick CO₂ atmosphere creating a runaway greenhouse effect, with surface temperatures of 500K.
Venus-like planets experience runaway greenhouse warming where CO₂ traps heat, evaporating oceans and creating hostile conditions despite being in the habitable zone.
Classification Criteria:
✓ Temperature: 500K (500-800K range)✓ CO₂-rich atmosphere creating greenhouse effect
Habitability ScoreExtremely Harsh

Contributing Factors
water50
Water present but likely as steam
geology90
Active geology recycles nutrients and drives carbon cycle
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
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.
