Arcseconds symbol

- The parsec (
**symbol**: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years or 206,000 astronomical units (au), i.e. 30.9 trillion kilometres (19.2 trillion miles). Parsec is obtained by the use of parallax and trigonometry, and is defined as the distance at which 1 au subtends an angle of one. . . - A unit of angle measurement, also called the minute of arc, equal to 60
**arcseconds**and to 1/60 degree. There are 21 600 arcminutes in a circle. Care is needed not to confuse**symbols**with units of length or time. The SI recommends ' as the**symbol**for - Full name:
