Overview
ℹī¸
FSR 0448 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a moderate 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 distance parameter (see Parameters). It is moderately studied in the literature.
