Puppis
Encyclopedia
Puppis is a constellation
in the southern sky. Its name is the Latin
word for the poop deck
of a ship, and Puppis represents the deck of the ship and its deckhouses. Puppis was originally part of an over-large constellation, the ship of "Jason and the Argonauts", Argo Navis
, which was centuries later 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.
systems have been found around stars in the constellation Puppis, including:
runs through Puppis, there are a large number of open cluster
s in the constellation. Messier 46 (M46) and Messier 47 (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
