Overview

ℹ️

Berkeley 59 is a very rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.

Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.
