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 Angular Distance Calculator

Compute the angular separation in degrees between any two celestial objects using their right ascension and declination coordinates. Use it to plan conjunction observations, check alignment of planets, or assess how close two stars appear in the sky.
