Overview
CWNU 275 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by low extinction. It is catalogued as a metal-rich, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is poorly studied in the literature.
