Overview

ℹ️

CWNU 132 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-poor, 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 (~1.87 kpc) differs significantly from the median photometric distance (~1.38 kpc).
