Overview

ℹ️

BDSB 73 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~1.69 kpc) differs significantly from the median photometric distance (~1.11 kpc).

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