Overview

ℹ️

BDSB 115 is a sparse, 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 an extremely massive, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~2.57 kpc) differs significantly from the median photometric distance (~7.96 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.
