Overview
CWNU 236 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.
