The parsec in turn is defined to be a certain multiple of the astronomical unit original such that the parallax of a star as it appears from the Earth is 1 arcsecond.    From Wordnik.com.  [The Speculist: Um, no] Reference

In astronomy, the preferred unit of measurement for such distances is the parsec, which is defined as the distance at which an object will appear to move one arcsecond of parallax when the observer moves one astronomical unit perpendicular to the line of sight to the observer.    From Wordnik.com.  [Ann Aguirre » Blog Archive » A day in the life – blog Jeopardy] Reference
