Overview

ℹ️

BDSB 132 is a poorly populated, loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 13 years.

⚠️ Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~2.13 kpc) differs significantly from the median photometric distance (~11.40 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.35) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Extremely distant

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.

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