Overview
ESO 226 06 is a poorly populated, 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 near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.
(*): The parallax distance estimate (~2.64 kpc) differs significantly from the median photometric distance (~1.76 kpc).
