Overview

ℹ️

UFMG 78 is a rich, dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a very metal-poor, 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.
