Overview

ℹ️

VDBH 78 is a moderately populated, 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 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 (~8.29 kpc) differs significantly from the median photometric distance (~5.59 kpc).
