Overview

ℹ️

CWNU 4837 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large^* distance, well below the mid-plane, affected by low extinction. It is catalogued as an extremely old cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~6.55 kpc) differs significantly from the median photometric distance (~10.23 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.

Extremely distant Low extinction Extremely old
