Overview

ℹ️

CWNU 2149 is a poorly populated, very dense object of low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It was recently reported in the literature.

Relatively close High extinction Near-solar metallicity Intermediate age
