Overview
UFMG 90 is a moderately populated, 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, very metal-poor, intermediate-age cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~2.18 kpc) differs significantly from the median photometric distance (~1.60 kpc).
Note: This object shares a moderate percentage of members with a later reported entry. See table with shared members information.
