Overview
ℹ️
Melotte 104 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 moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is very well-studied in the literature.
Relatively close Moderate extinction Massive Near-solar metallicity Intermediate age
