Overview

ℹ️

FSR 1580 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a very large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~10.24 kpc) differs significantly from the median photometric distance (~4.50 kpc).
