Overview
CWNU 1086 is a poorly populated, very dense object of high 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, very young cluster, but with a large variance across recent sources for the absorption and metallicity parameters (see Parameters). It is poorly studied in the literature.
