Overview
FSR 0291 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a large* distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~7.67 kpc) differs significantly from the median photometric distance (~5.14 kpc).
