Overview

ℹ️

FSR 0558 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above 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 age and mass parameters (see Parameters). It is moderately studied in the literature.

Relatively close High extinction Near-solar metallicity Intermediate age
