Overview
CWNU 1143 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a very close distance, above the mid-plane. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is poorly studied in the literature.
