Overview

ℹ️

UBC 1604 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a metal-rich, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.
