Overview
ℹī¸
VDBH 131 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 massive, near-solar metallicity, old cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~8.16 kpc) differs significantly from the median photometric distance (~5.50 kpc).
