The equatorial describes the sky as seen from the Solar System, and modern star maps almost exclusively use equatorial coordinates. The equatorial system is the normal coordinate system for most professional and many amateur astronomers having an equatorial mount that follows the movement of the sky during the night. Celestial objects are found ...
"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 ...
In 1958 the International Astronomical Union (IAU) decided to adopt the position of Sagittarius A as the true zero coordinate point for the system of galactic latitude and longitude. [11] In the equatorial coordinate system the location is: RA 17 h 45 m 40.04 s, Dec −29° 00′ 28.1″ (J2000 epoch).
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.
Chart of lunar maria with lines of longitude and latitude. The prime meridian is the centre of the near side of the Moon.. A planetary coordinate system (also referred to as planetographic, planetodetic, or planetocentric) [1] [2] is a generalization of the geographic, geodetic, and the geocentric coordinate systems for planets other than Earth.
A reference frame has been defined as "a catalogue of the adopted coordinates of a set of reference objects that serves to define, or realize, a particular coordinate frame". [7] A reference system is a broader concept, encompassing "the totality of procedures, models and constants that are required for the use of one or more reference frames".
The primary map is surrounded on all sides by detailed scientific calculations and descriptions as well as Northern and Southern Hemisphere star charts, a map of the Moon, a latitude and longitude analemma chart, a map of the Solar System, a mercator projection of the Earth, an analemma projection, a seasonal chart, a universal scale chart, and numerous smaller diagrams depicting planets and ...
Its center of coordinates as the center of mass of the entire Solar System, its barycenter. It was created in 2000 by the International Astronomical Union (IAU) to be the global standard reference system for objects located outside the gravitational vicinity of Earth : [ 1 ] planets, moons, and other Solar System bodies, stars and other objects ...
