Overview
ℹī¸
DBSB 3 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below 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 mass parameter (see Parameters). It is well-studied in the literature.
Distant Moderate extinction Near-solar metallicity Very young
