Overview

ℹ️

UBC 461 is a moderately populated, loose object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.

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