Overview

ℹ️

UBC 199 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is poorly studied in the literature.
