Examples of parsec
parsec
The unit of time, then has as many seconds as there are decimetres in a parsec.
From the en.wikipedia.org
This defines the parsec, a convenient unit for measuring distance using parallax.
From the en.wikipedia.org
The AU is too small for interstellar distances, where the parsec is commonly used.
From the en.wikipedia.org
A parsec is the distance at which a star's parallax as viewed from Earth is equal to one second of arc.
From the en.wikipedia.org
The astronomical distance unit parsec uses the AU as a baseline and an angle of one arcsecond for parallax.
From the en.wikipedia.org
Oh, that's what a parsec is.
From the techcrunch.com
In some cases, specialized units are used, such as the astronomer's parsec and light year or the particle physicist's barn.
From the en.wikipedia.org
That would be somewhere orbiting the star Epsilon Eridani, just a hop, skip and parsec from Earth, or 10.5 light-years to be exact.

Annex B lists some other non-SI units of space and time, namely the gon, light year, astronomical unit, parsec, tropical year, and gal.

- A unit of astronomical length based on the distance from Earth at which stellar parallax is 1 second of arc; equivalent to 3.262 light years
- The parsec (parallax of one arcsecond; symbol: pc) is a unit of length, equal to just under 31 trillion kilometres (about 19 trillion miles), or about 3.26 light-years. The parsec measurement unit is used in astronomy. ...
- PARSEC is a package designed to perform electronic structure calculations of solids and molecules using density functional theory (DFT). The acronym stands for Pseudopotential Algorithm for Real-Space Electronic Calculations. . ...
- Parsec is a computer game for the Texas Instruments TI-99/4A. Perhaps the best-remembered of all TI-99/4A games, it is a side-scrolling shooter, programmed in 1982 by Jim Dramis (who also programmed the popular TI-99/4A games Car Wars and Munch Man) and Paul Urbanus.
- Parallax second
- The distance at which a star must lie in order that its measured parallax is exactly 1 arc second, equal to 206,000 A.U.
- The distance from which the mean distance of Earth's orbit around the Sun, the astronomical unit (AU), appears under the angle of 1 arc second. Here, we prefer to use the light year; 1 pc = 3.26 ly. More acurately:
- The distance a star has to be to have a parallax shift of 1 arcsecond. (No star is actually this close). 1 parsec = 3.2616 light years.
- Unit of distance. 3.09 x 10^13 km or 206265 AU or 3.3 light year
