Overview

â„šī¸
UFMG 45 is a moderately populated, moderately 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 low-mass, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.

Note: This object shares a significant percentage of members with a later reported entry. See table with shared members information.

Relatively close Moderate extinction Low mass Near-solar metallicity Intermediate age
