Exoplanet Habitable Zone Calculator vs Gravitational Time Dilation 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
Gravitational Time Dilation Calculator
Calculates how gravity slows time near massive objects using Einstein's general relativity. Use it when comparing elapsed time at different distances from a planet, star, or black hole.
- Answers
- Time at Infinity (hours)
- Inputs
- Mass of Gravitating Body, Distance from Center, Proper Time
