Overview

ℹ️

UBC 1461 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by moderate extinction. It is catalogued as a metal-poor, old 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 moderate percentage of members with a later reported entry. See table with shared members information.
