Overview

ℹ️

FoF 458 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~2.65 kpc) differs significantly from the median photometric distance (~1.61 kpc).

Relatively close Moderate extinction Near-solar metallicity Intermediate age
