Overview

ℹ️

FSR 0815 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.89 kpc) differs significantly from the median photometric distance (~2.15 kpc).

Relatively close High extinction Low mass Intermediate age
