Overview

ℹ️

FSR 0165 is a rich, very 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, very young cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is well-studied in the literature.

Relatively close High extinction Near-solar metallicity Very young

Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.
