Astronomy Calculator
Calculate stellar distances, brightness ratios, and astronomical measurements
How to use: Calculate stellar distances and brightness for astronomy research. Select Distance (d = 1/p) to convert parallax to parsecs, Brightness Ratio to compare star luminosity using magnitude difference, or Light Years to convert parsecs to light-years (1 parsec = 3.26 light-years). Parallax is measured in arcseconds (smaller values = farther stars). Apparent magnitude scale: Lower numbers are brighter (Sun = -26.7, Sirius = -1.46, faintest naked-eye stars ≈ +6). Essential for astrophysics, stellar observation, and space science calculations.
