Overview
ℹī¸
VDBH 54 is a moderately populated, 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, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.
Relatively close Moderate extinction Near-solar metallicity Very young
