Overview

ℹ️

CWNU 1954 is a poorly populated, loose object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.

Relatively close High extinction Near-solar metallicity Old
