Overview
UFMG 87 is a rich, very 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 massive, 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.
(*): The parallax distance estimate (~3.41 kpc) differs significantly from the median photometric distance (~2.19 kpc).
Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.
