Overview
ℹī¸
ESO 522 05 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by very high extinction. It is catalogued as a near-solar metallicity, old cluster (see Parameters). It is moderately studied in the literature.

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