A parsec was an astronomical measure of length that stood for "parallax arc-second". It was based on the Earth method of measuring interstellar distances using trigonometry. A star located one parsec away from an observer would have a "parallax angle" of one arc-second.
A parsec (or parallax arc-second) is a unit of astronomical measurement, equal to roughly 3.26 light years. It was in common use by the United Federation of Planets in the 23rd and 24th centuries...
16 maj 2015 · As you probably know, Parsec is an abbreviation for parallax of one arcsecond and is a technique invented in 1913 which allows astronomers to measure the distance of various objects in the night sky, from planets in our own solar system to far off stars.
A parsec is a unit of distance measurement, equal to 3.262 light-years (31 trillion kilometres or 19.2 trillion miles). One parsec is the distance at which one astronomical unit subtends an angle of one arc-second. The parsec measurement was often used to measure stellar cartography by starship navigators.

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 206,265 astronomical units (AU), i.e. 30.9 trillion kilometres (19.2 trillion miles).
29 lip 2022 · A parsec is a unit of distance that is often used by astronomers as an alternative to the light-year, just as kilometers can be used as an alternative to miles. Sci-fi franchises such as "Star...
According to the pretty general definition of the Star Trek Encyclopedia, a sector is a space region with a diameter of 20 ly, although some official maps further specify a sector in the three-dimensional space as a cubic volume.
