Overview

ℹ️

DBSB 120 is a poorly populated, loose object of very low C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by high extinction. It is catalogued as an extremely massive, very young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~1.95 kpc) differs significantly from the median photometric distance (~5.48 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 High extinction Extremely massive Very young

Morales et al. (2013)
Classified as morphological type 'EC2' (partially embedded cluster). Morphological flag: cluster partially embedded, presence of emission related to PAH or warm dust.
