Overview

ℹ️

DBSB 73 is a sparse, moderately dense object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by high extinction. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~2.64 kpc) differs significantly from the median photometric distance (~4.53 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Distant High extinction Very young

Dutra et al. (2003)
Classified as stellar group (IRGr).
