Overview
UBC 1222 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.
Note: This object shares a significant percentage of members with a later reported entry. See table with shared members information.
