==Nomenclature== The name ''Canopus'' is a Latinisation of the [[Ancient Greek]] name Κάνωβος/Kanôbos, recorded in Claudius Ptolemy's ''[[Almagest]]'' (c.150 AD). Eratosthenes used the same spelling.<ref name="ridpathCr"/> Hipparchos wrote it as Κάνωπος. [[John Flamsteed]] wrote Canobus,<ref>{{cite book|last=Flamsteed|first=John|title=Atlas coelestis|location=London, United Kingdom|date=1729|pages=Constellation Map of Southern Hemisphere|url=https://gallica.bnf.fr/ark:/12148/btv1b53096741t/f108.item.zoom}}</ref> as did [[Edmond Halley]] in his 1679 ''Catalogus Stellarum Australium''.<ref name="Halley 1679">{{cite book|last=Halley|first=Edmond|title=Catalogus stellarum australium; sive, Supplementum catalogi Tychenici, exhibens longitudines et latitudines stellarum fixarum, quae, prope polum Antarcticum sitae, in horizonte Uraniburgico Tychoni inconspicuae fuere, accurato calculo ex distantiis supputatas, & ad annum 1677 completum correctas...Accedit appendicula de rebus quibusdam astronomicis|publisher=T.

It is listed in the [[Bright Star Catalogue]] as HR 2326, the [[Henry Draper Catalogue]] as HD 45348, and the [[Hipparcos catalogue]] as HIP 30438.<ref name=SIMBAD/> Flamsteed did not number this southern star, but [[Benjamin Apthorp Gould]] gave it the number 7 (7 G.
