Overview

ℹ️

CWNU 2430 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by very high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.
