Image in which there are four clusters (M46 on the left, NGC 2423 on the top right, M47 on the right, NGC 2425 on the bottom towards the center) and two small planetary nebulae, NGC 2438 and PN M 1-18 recognizable by its small red disk.

 

Messier 46 (M46) or NGC 2437, is an open cluster of stars in Puppis constellation at about 5,000 light-years.

The planetary nebula NGC 2438 appears on its northern edge, but it is unrelated with the cluster.

Messier 47 (M47) or NGC 2422, is an open cluster in Puppis at about 1.600 light-years.

NGC 2423 It is another cluster to the north of M47 at about 2,500 light-years.

NGC 2425 (to the southeast) is further away and smaller (5 arcmin) with an age of 2.2 Gy.
