Overview

ℹ️

UBC 61 is a poorly populated, very dense object of low C3 quality. Its parallax locates it at a relatively close distance, below 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.
