Editing Stellar designations and names (section)

===By constellation===
The first modern schemes for designating stars systematically labelled them within their constellation.

*The [[Bayer designation]] is such a system, published by [[Johann Bayer]] in 1603.<ref>{{cite web|url=http://www.ianridpath.com/startales/bayer.htm|title=Bayer's Uranometria and Bayer letters|publisher=Ian Ridpath|access-date=2016-11-12}}</ref> It introduced a system of designating the brightest stars in each constellation by means of Greek (or less often Latin) letters, and is still widely used. Bayer generally assigned letters by magnitude class: 1st magnitude stars received the earliest letters in the alphabet, followed by 2nd magnitude stars, and so forth (though there are many exceptions).  The original list of Bayer designations contained 1,564 naked-eye stars, and several stars not catalogued by Bayer have been added by subsequent astronomers.
*The [[Flamsteed designation]] also lists stars by constellation, but by number rather than letter, ordering them by increasing right ascension rather than by decreasing brightness. These numbers were assigned not by Flamsteed himself but by the French astronomer J. J. Lalande in a French edition of Flamsteed's catalogue published in 1783.<ref>{{cite web|url=http://www.ianridpath.com/startales/flamsteed.htm|title=Flamsteed numbers – where they really came from|publisher=Ian Ridpath|access-date=2016-11-12}}</ref>
*The [[Gould designation]] for stars visible from the southern hemisphere, introduced by [[Benjamin Gould]] (1879), also lists stars by constellation, numbered by increasing right ascension.
*[[Hevelius]] and [[Johann Elert Bode|Bode]] both numbered stars within constellations similarly. Their number systems have fallen out of use, but their designations even now are occasionally mistakenly treated as Flamsteed designations.  [[47 Tucanae]], a number assigned by Bode, is a famous example.
