Astronomy
Distance Modulus Calculator
Compute distance to a celestial object in parsecs from its apparent and absolute magnitudes using the distance modulus formula d = 10^((m β M + 5)/5). The standard "standard candle" technique for measuring distances across the Milky Way and to nearby galaxies.

Astronomy
Stellar Parallax Calculator
Convert a star's measured parallax angle into its distance from Earth in parsecs. Used by astronomers to determine distances to nearby stars from annual parallax shift observations.
