Overview

ℹ️

FSR 1746 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.62 kpc) differs significantly from the median photometric distance (~4.10 kpc).
