Overview

ℹ️

FoF 2000 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, above 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.

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

Relatively close Moderate extinction Near-solar metallicity Intermediate age
