Overview
UBC 662 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 moderate extinction. It is catalogued as a metal-poor, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
