Overview
ℹ️
ESO 211 03 is a rich, very dense object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is moderately studied in the literature.

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

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