Overview

ℹ️

DBSB 39 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.77 kpc) differs significantly from the median photometric distance (~2.12 kpc).

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
