About these units
Light Years (ly)
A light-year is the distance light travels through a vacuum in one Julian year, about 9.461 trillion kilometers. Despite the name it measures distance, not time, and is used for stars and galaxies.
Parsecs (pc)
A parsec is the distance at which one astronomical unit subtends an angle of one arcsecond, about 3.26 light-years or 30.9 trillion kilometers. Astronomers use it for distances to stars.
