Overview

ℹ️

FoF 589 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 low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the absorption, age, and metallicity parameters (see Parameters). It is moderately studied in the literature.

Note: This object shares a large percentage of members with 3 later reported entries. See table with shared members information.

Relatively close Low extinction Near-solar metallicity Intermediate age
