Overview

ℹ️

UBC 473 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a large 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 parameter (see Parameters). It is rarely studied in the literature.

Distant Moderate extinction Near-solar metallicity Intermediate age
