Overview
BDSB 128 is a sparse, very loose object of very 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.
(*): The parallax distance estimate (~2.30 kpc) differs significantly from the median photometric distance (~1.56 kpc).
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
