Moderate Activity
Why is this a Venus Like?Your planet has a thick CO₂ atmosphere creating a runaway greenhouse effect, with surface temperatures of 573K.
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: 573K (500-800K range)✓ CO₂-rich atmosphere creating greenhouse effect

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
atmosphere14
Dense CO₂ atmosphere with extreme greenhouse effect (partially stripped by slow rotation)
temperature15
Extremely hot - hostile to known life forms
magnetic Field30
No magnetic field - vulnerable to solar radiation
