Astronomy
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.

Astronomy
Asteroid Impact Energy Calculator
Calculate the kinetic energy released when an asteroid strikes Earth, expressed in megatons of TNT. Use it to compare historical impacts or assess the potential effect of a hypothetical impactor.
