Overview
ℹī¸
FSR 1197 is a moderately populated, moderately dense object of high C3 quality. Its parallax locates it at a close* distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, old cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~0.85 kpc) differs significantly from the median photometric distance (~1.24 kpc).
