  2. Galactic plane - Wikipedia

    en.wikipedia.org/wiki/Galactic_plane

    The galactic plane is the plane on which the majority of a disk-shaped galaxy's mass lies. The directions perpendicular to the galactic plane point to the galactic poles . In actual usage, the terms galactic plane and galactic poles usually refer specifically to the plane and poles of the Milky Way , in which Planet Earth is located.

  3. Galactic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Galactic_coordinate_system

    The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way Galaxy, and the fundamental plane parallel to an approximation of the galactic plane but offset to its north.

  4. PALFA Survey - Wikipedia

    en.wikipedia.org/wiki/PALFA_Survey

    Galactic location of the new P-ALFA pulsar survey discoveries. The center of the Galaxy is indicated by the center of the coordinates, the position of the Solar System is indicated by the red dot on the left. The PALFA search areas are indicated in light blue. The dots indicate pulsars, this time colored according to their DM.

  5. Astronomical coordinate systems - Wikipedia

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

    The galactic coordinate system uses the approximate plane of the Milky Way Galaxy as its fundamental plane. The Solar System is still the center of the coordinate system, and the zero point is defined as the direction towards the Galactic Center. Galactic latitude resembles the elevation above the galactic plane and galactic longitude ...

  6. Supergalactic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Supergalactic_coordinate...

    The origin essentially coincides with the Earth, because the supergalactic plane is identified as a plane observed from Earth. The north supergalactic pole (SGB = 90°) lies in the constellation Hercules at galactic coordinates (l z = 47.37°, b z = +6.32°), or approximately RA = 18.9 h, Dec = +15.7°.

    en.wikipedia.org/wiki/Galactic_quadrant

    "Galactic quadrants" within Star Wars canon astrography map depicts a top-down view of the galactic disk, with "Quadrant A" (i.e. "north") as the side of the galactic center that Coruscant is located on. As the capital planet of the Republic and later the Empire, Coruscant is used as the reference point for galactic astronomy, set at XYZ ...

  9. Milky Way - Wikipedia

    en.wikipedia.org/wiki/Milky_Way

    The galactic plane is inclined by about 60° to the ecliptic (the plane of Earth's orbit). Relative to the celestial equator, it passes as far north as the constellation of Cassiopeia and as far south as the constellation of Crux, indicating the high inclination of Earth's equatorial plane and the plane of the ecliptic, relative to the galactic ...
