Overview
CWNU 1013 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a very close distance, near the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It is poorly studied in the literature.
Note: This object shares a very small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
