Overview

ℹ️

CWNU 19 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Young
