Overview
ℹ️
Juchert 13 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is moderately studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Note: This object shares a moderate percentage of members with a later reported entry. See table with shared members information.
