Overview

ℹ️

Juchert 1 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is very well-studied in the literature.

Distant High extinction Near-solar metallicity Intermediate age

Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.
