Overview

ℹ️

UBC 417 is a poorly populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, below 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 metallicity parameter (see Parameters). It is moderately studied in the literature.

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