Overview

ℹ️

CWNU 58 is a moderately populated, very loose object of intermediate C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.
