Overview

ℹ️

Berkeley 69 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is very well-studied in the literature.

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

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

Distant Moderate extinction Near-solar metallicity Intermediate age Contains BSS
