Overview

ℹ️

Berkeley 36 is a very rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster (see Parameters). It is well-studied in the literature.

Note: This object shares a very small percentage of members with 2 later reported entries. See table with shared members information.
