As the [[Milky Way]] runs through Puppis, there are many [[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. [[Open Cluster M93|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]].

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, despite not being at its center. The cluster's stars, numbering between 50 and 100, have a moderate range in brightness.{{sfn|Levy|2005|pp=85-86}}
