About Parsec (pc)

Approximately 3.26 light-years (30.857 trillion km), the parsec is defined as the distance at which one astronomical unit subtends one arcsecond of parallax. Professional astronomers prefer parsecs over light-years because parsecs relate directly to the trigonometric parallax method used to measure stellar distances.
