Overview

ℹ️

CWNU 6 is a poorly populated, dense object of low C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by moderate 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 is poorly studied in the literature.

(*): The parallax distance estimate (~1.70 kpc) differs significantly from the median photometric distance (~1.29 kpc).

Relatively close Moderate extinction Near-solar metallicity Intermediate age
