Gene Roddenberry, Galactic Quadrants from Star Trek, 2010

'"Galactic quadrants" within Star Trek are based around a meridian that runs from the center of the galaxy through Earth's solar system, which is not unlike the system used by astronomers. However, rather than have the perpendicular axis run through the Sun, as is done in astronomy, the Star Trek version runs the axis through the galactic center. In that sense, the Star Trek quadrant system is less-geocentric as a cartographical system than the standard. Also, rather than use ordinals, Star Trek designates them by the Greek letters Alpha, Beta, Gamma, and Delta.'
