Overview

ℹ️

FSR 1607 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, well below the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.31 kpc) differs significantly from the median photometric distance (~1.56 kpc).

Relatively close Low extinction Old
