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.

Astronomy
Planetary Temperature Calculator
Estimate a planet's equilibrium temperature based on its host star's temperature, radius, and the planet's orbital distance. Useful for assessing whether exoplanets might fall within a habitable zone.
