Overview

ℹ️

UPK 294 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate 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 moderately studied in the literature.

Close Moderate extinction Near-solar metallicity Intermediate age
