Overview

ℹ️

VDBH 118 is a rich, very dense object of high C3 quality. Its parallax locates it at a very large^* distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~10.16 kpc) differs significantly from the median photometric distance (~7.73 kpc).
