Overview
ℹī¸
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 mass parameter (see Parameters). It is very well-studied in the literature.
Relatively close High extinction Near-solar metallicity Very young

Almeida et al. (2025)
Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.

Cavallo et al. (2024)
Gold sample.
