Overview

ℹ️

FSR 1617 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.65 kpc) differs significantly from the median photometric distance (~1.83 kpc).

Relatively close Moderate extinction Intermediate age
