Overview
UBC 1025 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.
