The parsec ("parallax of one arcsecond", symbol pc) is a unit of length, equal to just over 30 trillion kilometres, or about 3.26 light years. The parsec is used in astronomy.
The parsec is defined as the length of the adjacent side of an imaginary right triangle in space. The two dimensions that this triangle is based on are the angle (which is defined as 1 arcsecond), and the opposite side (which is defined as 1 Astronomical Unit, which is the distance from the Earth to the sun). Using these two measurements, along with the rules of trigonometry, the length of the adjacent side (the parsec) can be found.(Wikipedia)
The term parsec is first used by Herbert Hall Turner in 1913 from an astronomical publication.
One parsec is approximately 3.262 light-years, that is, the distance traveled by light in 3.26 earth years.
The parsec is a unit of distance in space and when we mean distance, it is how far we traveled. Traveling would mean an account for speed.
