Overview

ℹ️

FSR 1163 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is moderately studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Old
