3.26 LY or 206,265 AU

The parsec unit is defined as the distance at which 1 AU subtends an angle of one arcsecond (⁠1/3600⁠ of a degree). Kind of handy when an AU Astronomical Unit is the distance from the Sun to Earth and you're on Earth looking through a telescope trying to measure distances by their arc movement over a night.
