These former constellations are often found in older books, star charts, or star catalogues. The 88 modern constellation names and boundaries were standardised by Eugene Delporte for the IAU in 1930, under an international agreement, removing any possible astronomical ambiguities between astronomers from different countries.

In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...

The star names (prefixed with MUL 𒀯) are listed with the associated deity (prefix DINGIR ð’€) and often some other brief epithet. dates of heliacal risings; pairs of constellations which rise and set simultaneously; time-intervals between dates of heliacal risings; pairs of constellations which are simultaneously at the zenith and at the ...
Most northern constellations date to antiquity, with names based mostly on Classical Greek legends. [11] Evidence of these constellations has survived in the form of star charts, whose oldest representation appears on the statue known as the Farnese Atlas, based perhaps on the star catalogue of the Greek astronomer Hipparchus. [43]
Rather, star names are selected on a non-commercial basis by a small number of international organizations of astronomers, scientists, and registration bodies, who assign names consisting usually of a Greek letter followed by the star's constellation name, or less frequently based on their ancient traditional name.
The constellation Argo Navis as shown by Johannes Hevelius The ship in animated dark-to-lighter-to-dark sky and then illustrated with a stick-figure drawing. Argo Navis (the Ship Argo), or simply Argo, is one of Ptolemy's 48 constellations, now a grouping of three IAU constellations. It is formerly a single large constellation in the southern ...
