As the Milky Way runs through Puppis, there are a large number of open clusters in the constellation.[[Messier 46]] and [[Messier 47]] 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. | As the Milky Way runs through Puppis, there are a large number of open clusters in the constellation.[[Messier 46]] and [[Messier 47]] are two open clusters in the same binocular field.

M46 is a circular open cluster with an overall magnitude of 6.1 at a distance of approximately 5400 light-years from Earth. The planetary nebula NGC 2438 is superimposed; it is approximately 2900 light-years from Earth. M46 is classified as a Shapley class f and a Trumpler class III 2 m cluster. This means that it is a rich cluster that appears distinct from the star field; however, it is not at its center. The cluster's stars, numbering between 50 and 100, have a moderate range in brightness.[ | M46 is a circular open cluster with an overall magnitude of 6.1 at a distance of approximately 5400 light-years from Earth.
