    en.wikipedia.org/wiki/Galactic_quadrant

    Quadrants are described using ordinals—for example, "1st galactic quadrant", [1] "second galactic quadrant", [2] or "third quadrant of the Galaxy". [3] Viewing from the north galactic pole with 0 degrees (°) as the ray that runs starting from the Sun and through the galactic center, the quadrants are as follows (where l is galactic longitude):

    It is located in the first galactic quadrant at a distance of 3 kpc (about 10,000 ly) from the Galactic Center. [223] [224] A simulation published in 2011 suggested that the Milky Way may have obtained its spiral arm structure as a result of repeated collisions with the Sagittarius Dwarf Elliptical Galaxy.

    In one system, the U axis is directed toward the Galactic Center (l = 0°), and it is a right-handed system (positive towards the east and towards the north galactic pole); in the other, the U axis is directed toward the galactic anticenter (l = 180°), and it is a left-handed system (positive towards the east and towards the north galactic ...

    It is one of the spiral arms of the Milky Way and it is located in the first galactic quadrant at a distance of 3 kiloparsecs (9,800 light-years) from the Galactic Center. Along with the Near 3 kpc Arm, the existence of which has been known since the mid-1950s, the counterpart inner arms establish the symmetry of the Milky Way. [1]

    Galactic quadrant – in Star Trek, the Milky Way galaxy is divided into four galactic quadrants: Alpha, Beta, Delta and Gamma. Galactic Core – central area of the Milky Way galaxy, lying partially in each of the four galactic quadrants. Sector – a sector was a volume of space approximately twenty light years across.

    en.wikipedia.org/wiki/Astronomical_coordinate...

    In astronomy, coordinate systems are used for specifying positions of celestial objects (satellites, planets, stars, galaxies, etc.) relative to a given reference frame, based on physical reference points available to a situated observer (e.g. the true horizon and north to an observer on Earth's surface).
