Overview

ℹ️

VDBH 19 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near 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 parameter (see Parameters). It is well-studied in the literature.

Distant Moderate extinction Near-solar metallicity Intermediate age
