Overview

ℹ️

CWNU 3 is a poorly populated, dense object of low C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is rarely studied in the literature.
