Overview

ℹ️

Berkeley 46 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, well above the mid-plane, affected by low extinction. It is catalogued as an extremely massive, near-solar metallicity, very old 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.

Note: This object contains blue stragglers according to at least one source.

Distant Low extinction Extremely massive Near-solar metallicity Very old Contains BSS
