Overview

ℹ️

FSR 0023 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~3.55 kpc) differs significantly from the median photometric distance (~2.42 kpc).

Relatively close High extinction Massive Intermediate age
