About Light-year (ly)

The distance light travels in one Julian year -- approximately 9.461 trillion kilometers -- the light-year is the standard unit for expressing interstellar distances. Proxima Centauri, the nearest star beyond the Sun, lies about 4.24 light-years away. Despite its name, the light-year measures distance, not time.

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.
