Overview

ℹ️

FSR 0941 is a rich, loose object of high C3 quality. Its parallax locates it at a large distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is well-studied in the literature.

Distant Moderate extinction Massive Near-solar metallicity Intermediate age
