Overview

ℹ️

CWNU 1762 is a poorly populated, moderately dense object of very high C3 quality. Its parallax locates it at a large distance, above the mid-plane, affected by low extinction. It is catalogued as a metal-poor, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.
