For alternative uses, see [[Dorado (disambiguation)]].'' '''Dorado''' ({{pronEng|dɒˈrɑːdoʊ}}, {{lang-es|[[mahi-mahi]] ''or'' dolphin-fish}}) is a southern [[constellation]]. The constellation was one of twelve constellations created by [[Pieter Dirkszoon Keyser]] and [[Frederick de Houtman]] between 1595 and 1597, and it first appeared in [[Johann Bayer]]'s ''[[Uranometria]]'' of 1603. It is also known as '''Xiphias''' or the '''Sword-fish'''. The name Dorado is not a [[Latin]] word, but is a Spanish descendant of Latin ''dē-aurātus'' = "gilded", but as a constellation name it is treated (by analogy of the adjacent old constellation [[Argo Navis]]) like a feminine proper name of Greek origin ending in -ō (like ''Io'' or ''Callisto'' or ''Argo'') with [[genitive]] ending in ''-ūs'' (Greek e.g. Καλλίστω - Καλλίστους). Dorado is notable for containing most of the [[Large Magellanic Cloud]], the remainder being in the constellation [[Mensa (constellation)|Mensa]]. The [[South Ecliptic Pole]] also lies within this constellation. == Notable stars == * [[S Doradus|S Dor]] 9.721 &ndash; hypergiant in the [[Large Magellanic Cloud]], [[S Dor variable]] prototype *[[SN1987A|Supernova 1987A]] is the closest supernova since the invention of the telescope. * The variable star [[R Doradus]] 5.73 &ndash; has the largest [[as of 1997|known]] size of any star.[http://simbad.u-strasbg.fr/cgi-bin/cdsbib?1997MNRAS.286..957B] *[[HE 0437-5439]], a [[hypervelocity star]] escaping from the [[Milky Way]]/[[Magellanic Cloud]] system *γ Dor, prototype of the γ Dor variable stars *See also the [[list of stars in Dorado]] ==Notable deep sky objects== Because Dorado contains part of the [[Large Magellanic Cloud]], it is rich in deep sky objects.
