Why is this a Venus Like?Your planet has a thick CO₂ atmosphere creating a runaway greenhouse effect, with surface temperatures of 593K.
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: 593K (500-800K range)✓ CO₂-rich atmosphere creating greenhouse effect
