parsec (pc) (informative)
1 parsec is the distance at which 1 astronomical unit subtends an angle of 1 second of arc. 1 pc = 206264,8 AU = 30,85678 x 10^15 m
[ISO 31-01:1992.1-03.B.c]


Parsec
The parsec ('parallax of one arcsecond', symbol pc) is a unit of length, equal to just over 30 trillion kilometres, or about 3.3 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.

Parsec
De parsec (meervoud: parsecs, afkorting: pc) is een afstandsmaat die gebruikt wordt in de astronomie. De naam parsec is afgeleid van de termen parallax en boogseconde. - Definitie De parsec is de afstand die men vanaf de Aarde de ruimte moet ingaan, om de gemiddelde afstand Aarde - zon onder een hoek van één boogseconde te zien.
