... A star at a distance of 1 parsec would have a parallax of one arcsecond – this is the definition of parsec, which is short for parallax arcsecond. A star at a distance of 2 parsecs would have a parallax of 0.5 arcsecond. So, measure the parallax, and you know the distance. The closest star, Proxima ...
