A celestial map by the Dutch cartographer Frederik de Wit, 1670. A star chart is a celestial map of the night sky with astronomical objects laid out on a grid system. They are used to identify and locate constellations, stars, nebulae, galaxies, and planets. [1] They have been used for human navigation since time immemorial. [2]
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 ...

A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
The whole set of star maps contained 1,300 stars. The Dunhuang map or Dunhuang Star map is one of the first known graphical representations of stars from ancient Chinese astronomy, dated to the Tang dynasty (618–907). Before this map, much of the star information mentioned in historical Chinese texts had been questioned. [2]
19 Tauri is the system's Flamsteed designation.It also bears the little-used Bayer designation q Tauri.The designations of the two constituents as 19 Tauri A and B, and those of A's components - 19 Tauri Aa and Ab - derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).
