Exoplanet Habitability Calculator vs Exoplanet Habitable Zone Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Exoplanet Habitability Calculator
Estimate an exoplanet's effective surface temperature and habitability based on its host star and orbital parameters. Use this when evaluating whether a discovered or hypothetical planet could support liquid water.
- Answers
- Surface Temperature (Kelvin)
- Inputs
- Stellar Luminosity, Stellar Temperature, Orbital Distance, Atmosphere Type
Exoplanet Habitable Zone Calculator
Estimate the inner and outer boundaries of a star's habitable zone based on its luminosity, spectral type, and a planet's mass. Use it when assessing whether a known exoplanet could support liquid water on its surface.
- Answers
- Optimal Habitable Distance (AU)
- Inputs
- Star Luminosity, Stellar Classification, Planet Mass
