Parsecs

Distances to the closest stars can be determined through measurement of their trigonometric parallax. The parsec was defined to be the distance at which 1 AU (perpendicular to the line of sight) subtends an angle of 1 arcsecond.

• Parsec (30,860,000,000,000,000 meters)

  The parsec (symbol: pc) is a unit of length used to measure large distances to astronomical objects outside the Solar System. A parsec is defined as the distance at which one astronomical unit subtends an angle of one arcsecond, which corresponds to 648000 / π astronomical units. One parsec is equal to about 3.26 light-years (30 trillion km or 19 trillion miles) in length. The nearest star, Proxima Centauri, is about 1.3 parsecs (4.2 light-years) from the Sun. Most of the stars visible to the unaided eye in the night sky are within 500 parsecs of the Sun.

• Chain (20.11684 meters)

  A chain is a unit of length that measures 66 feet, 22 yards, 100 links, or 4 rods (20.1168 m). There are 10 chains in a furlong, and 80 chains in one statute mile. An acre is the area of 10 square chains (that is, an area of one chain by one furlong). The chain has been used for several centuries in England and in some other countries influenced by English practice. In Scotland a chain was 74 feet.
