Overview
Juchert J0644.8-0925 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a large* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~9.29 kpc) differs significantly from the median photometric distance (~5.95 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
