Overview

ℹ️

Melotte 76 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is very well-studied in the literature.

Relatively close Low extinction Massive Near-solar metallicity Intermediate age
