Overview

ℹ️

FSR 1407 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, well above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, very old cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.

Distant Low extinction Near-solar metallicity Very old
