Puppis /ˈpʌpɪs/ is a constellation in the southern sky. Puppis, the Poop Deck, was originally part of an over-large constellation, the ship of "Jason and the Argonauts", Argo Navis, which centuries after its initial description was divided into three parts, the other two being Carina (the keel and hull), and Vela (the sails of the ship). Puppis is the largest of the three constellations in square degrees. It is one of the 88 modern constellations recognized by the International Astronomical Union.
Argo Navis was sub-divided into three sections 1752 by the French astronomer Nicolas Louis de Lacaille, including "Argûs in puppi". Despite the division, Lacaille kept a single set of Bayer designations for the whole constellation Argo. Therefore Carina has the α, β and ε, Vela has γ and δ, Puppis has ζ, and so on. In the 19th century, these three sections of Argo became established as separate constellations, and were formally included in the list of 88 modern IAU constellations in 1930.
Several extrasolar planet systems have been found around stars in the constellation Puppis, including:
As the Milky Way runs through Puppis, there are a large number of open clusters in the constellation. M46 and M47 are two open clusters in the same binocular field. M47 can be seen with the naked eye under dark skies, and its brightest stars are 6th magnitude. Messier 93 (M93) is another open cluster somewhat to the south. NGC 2451 is a very bright open cluster containing the star c Puppis and the near NGC 2477 is a good target for small telescopes. The star Pi Puppis is the main component of a bright group of stars known as Collinder 135.
