Overview

ℹ️

BDSB 133 is a sparse, very loose object of low C3 quality. Its parallax locates it at a relatively close^* 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.

(*): The parallax distance estimate (~1.95 kpc) differs significantly from the median photometric distance (~11.40 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.

Extremely distant

Morales et al. (2013)
Classified as morphological type 'EC2' (partially embedded cluster). Morphological flag: cluster partially embedded.
