Overview

ℹ️

UFMG 1 is a rich, 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 massive, near-solar metallicity, 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 (~1.90 kpc).

Note: This object shares a large percentage of members with 4 later reported entries. See table with shared members information.

Relatively close Moderate extinction Massive Near-solar metallicity Intermediate age
