Overview

ℹ️

DBSB 85 is a poorly populated, loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a low-mass, young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.65 kpc) differs significantly from the median photometric distance (~2.02 kpc).

Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.97) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Relatively close High extinction Low mass 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.
