Overview

ℹ️

DBSB 64 is a sparse, loose object of low C3 quality. Its parallax locates it at a close^* distance, above the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~0.93 kpc) differs significantly from the median photometric distance (~3.08 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.
