Overview

ℹ️

UBC 82 is a moderately populated, moderately dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age 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.
