Overview
UFMG 46 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a moderate* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a very metal-poor, intermediate-age cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~2.67 kpc) differs significantly from the median photometric distance (~2.00 kpc).
