Overview

ℹ️

BDSB 129 is a moderately populated, 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.

⚠️ 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.

Relatively close

Morales et al. (2013)
