Overview

ℹ️

BSF 56 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 low-mass cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 23 years.

(*): The parallax distance estimate (~2.44 kpc) differs significantly from the median photometric distance (~1.40 kpc).

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.
