Overview
CWNU 356 is a moderately populated, dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption and metallicity parameters (see Parameters). It is rarely studied in the literature.
