Overview

ℹ️

FoF 1970 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Distant Low extinction Massive Near-solar metallicity Intermediate age

Mass determination: good fit. Isochrone match: intermediate fit.
