Overview
UBC 572 is a poorly populated, very dense object of very high 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, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.
Note: This object shares a significant percentage of members with a later reported entry. See table with shared members information.
