Overview

ℹ️

UPK 292 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a very close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is poorly studied in the literature.
