Overview
ℹī¸
FSR 1509 is a poorly populated, dense object of high C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.61 kpc) differs significantly from the median photometric distance (~3.82 kpc).
