Overview
CWNU 460 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It is rarely studied in the literature.
