Overview

ℹ️

DBSB 176 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high extinction. It is catalogued as an extremely massive, young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.43 kpc) differs significantly from the median photometric distance (~7.69 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.

Very distant Very high extinction Extremely massive Young

Morales et al. (2013)
Classified as morphological type 'OC0' (emerging exposed cluster). Morphological flag: possibly associated submm emission surrounding the cluster, presence of an IR bubble and possible YSOs.
