Overview

ℹ️

UBC 457 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is poorly studied in the literature.

Note: This object shares a large percentage of members with 2 later reported entries. See table with shared members information.

Relatively close Low extinction Near-solar metallicity Intermediate age
