Overview

ℹ️

Juchert 19 is a rich, very loose object of high C3 quality. Its parallax locates it at a large distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is poorly studied in the literature.
