Overview

ℹ️

FSR 1083 is a rich, very dense object of high C3 quality. Its parallax locates it at a large distance, well above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is well-studied in the literature.

Distant Low extinction Near-solar metallicity Old
