Overview

ℹ️

UBC 651 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

Distant Moderate extinction Near-solar metallicity Intermediate age
