Overview

ℹ️

VDBH 34 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~4.14 kpc) differs significantly from the median photometric distance (~0.95 kpc).
