Overview

ℹ️

FSR 0921 is a rich, very dense object of intermediate C3 quality. Its parallax locates it at a moderate distance, below 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 metallicity parameter (see Parameters). It is well-studied in the literature.

Relatively close High extinction Near-solar metallicity Intermediate age
