Overview

ℹ️

CWNU 1010 is a poorly populated, loose object of very high C3 quality. Its parallax locates it at a very close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is poorly studied in the literature.
