Overview

ℹ️

Loden 189 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~1.31 kpc) differs significantly from the median photometric distance (~0.82 kpc).
