Exoplanet Habitable Zone Calculator vs Stellar Lifetime 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 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
Stellar Lifetime Calculator
Estimate how long a star spends on the main sequence based on its mass relative to the Sun. More massive stars burn through fuel faster, living far shorter lives than smaller stars.
- Answers
- Main Sequence Lifetime (billion years)
- Inputs
- Stellar Mass
