Overview

ℹ️

UBC 580 is a poorly populated, loose object of low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.

Distant Moderate extinction Near-solar metallicity Very young
