Venus Like Magnetic Field Moderate Activity
Why is this a Venus Like? Your planet has a thick CO₂ atmosphere creating a runaway greenhouse effect, with surface temperatures of 643K. Venus-like planets experience runaway greenhouse warming where CO₂ traps heat, evaporating oceans and creating hostile conditions despite being in the habitable zone.
✓ Temperature: 643K (500-800K range) ✓ CO₂-rich atmosphere creating greenhouse effect
Habitability Score Uninhabitable
Contributing Factors water 50
Water present but likely as steam geology 90
Active geology recycles nutrients and drives carbon cycle rotation 100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution Organic Chemistry 80
Core organic elements (CHNO) present atmosphere 35
Dense CO₂ atmosphere with extreme greenhouse effect temperature 5
Scorching - hot enough to melt lead, though rock stays solid; no chance for life magnetic Field 100

Moon 1 stable 0.00010% - 100.0 radii
Small and distant: a quiet, stable companion.
Moon 2 rings 10% - 2.2 radii
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 3 merged 0.010% - 4.3 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
