Overview

ℹ️

CWNU 3648 is a sparse, very loose object of high C3 quality. Its parallax locates it at a very large^* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~36.50 kpc) differs significantly from the median photometric distance (~24.55 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.
