Parsec

dcterms:description

lang:""

The parsec (parallax of one arcsecond; symbol: pc) is a unit of length, equal to just under 31 trillion ($31 \times 10^{12}$) kilometres (about 19 trillion miles), 206265 AU, or about 3.26 light-years. The parsec measurement unit is used in astronomy. It is defined as the length of the adjacent side of an imaginary right triangle in space. The two dimensions that specify this triangle are the parallax angle (defined as 1 arcsecond) and the opposite side (defined as 1 astronomical unit (AU), the distance from the Earth to the Sun). Given these two measurements, along with the rules of trigonometry, the length of the adjacent side (the parsec) can be found.
