is a portmanteau of the words parallax and second. This is the distance at which a star would show a parallax shift of exactly one arcsecond as observed from Earth's orbit. It is equal to 3.2616 light years or 206,265 Astronomical Units.

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. It solves the Kohn–Sham equations in real space, without the use of explicit basis sets. One of the strengths of this cod...

A parsec (symbol: pc) is an astronomical unit of length used to measure distances to objects outside the Solar System. About 3.26 light-years (31 trillion kilometers or 19 trillion miles) in length, the parsec is shorter than the distance from our solar system to the nearest star, Proxima Centauri, which is 1.3 parsecs from the Sun. Nevertheless, ...

[video game] 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. == Object == The player in the Parsec pilots a spaceship thro...

A unit of distance equal to about 3.26 light-years (or, more precisely, equal to 206,265 Astronomical Units). Technically, a parsec is defined to be the distance from which the Earth and Sun would appear to be separated from one another by 1 second of arc (about the size a dime would appear to be if seen from a distance of 2 miles).
