Overview

ℹ️

FSR 0284 is a moderately populated, dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Young
