Overview

ℹ️

FoF 597 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.

Note: This object shares a large percentage of members with 2 later reported entries. See table with shared members information.

Relatively close Moderate extinction Massive Near-solar metallicity Intermediate age
