Overview

ℹ️

UBC 466 is a rich, loose object of intermediate C3 quality. Its parallax locates it at a large distance, below 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 metallicity parameter (see Parameters). It is poorly studied in the literature.

Distant Moderate extinction Near-solar metallicity Intermediate age
