Overview

ℹ️

FSR 1378 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is well-studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Intermediate age
