Description: The parsec is a unit of length equivalent to around 20 trillion (20,000,000,000,000) miles, 31 trillion kilometres, or 206,264 times the distance from the earth to the sun.efinition: Astronomers used trigonometry to calculate the distance to stars long before the term parsec was coined, but the new unit made it easier to conceptualise unfathomable distances. A parsec is the distance from the sun to an astronomical object which has a parallax angle of one arcsecond (1/3600 of a degree).
