Exoplanet Habitability Calculator

Estimate how potentially habitable a planet could be based on its star distance, temperature, gravity, atmosphere, and water availability.

Earth-like temperatures are usually more favorable for liquid water.
Extreme gravity may make surface life less likely.
A stable atmosphere helps regulate temperature and shielding.
Liquid water is one of the strongest indicators of habitability.
Frequent stellar flares can reduce long-term survivability.
Stable orbits help maintain long-term climate conditions.
How we calculate

We combine temperature, gravity, atmosphere, water, stellar radiation, and orbital stability into a simplified 0–100 score. Conditions closer to Earth-like ranges increase the estimate.
