Overview

ℹ️

CWNU 446 is a moderately populated, very dense object of intermediate C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is poorly studied in the literature.

Close Moderate extinction Near-solar metallicity Very young
