Overview

ℹ️

FSR 1380 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a moderate 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 metallicity parameter (see Parameters). It is moderately studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Distant Moderate extinction Near-solar metallicity Intermediate age Contains BSS
