Overview

ℹ️

CWNU 3953 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a large distance, near the mid-plane, affected by very high extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

⚠️ 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.

Very distant Very high extinction Very young
