Overview

ℹ️

VDBH 72 is a rich, very dense object of high C3 quality. Its parallax locates it at a large^* distance, below 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, metallicity, and mass parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.86 kpc) differs significantly from the median photometric distance (~4.55 kpc).

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