Overview

ℹ️

FSR 0125 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, well above the mid-plane, affected by low extinction. It is catalogued as a very massive, old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.95 kpc) differs significantly from the median photometric distance (~6.25 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Very distant Low extinction Very massive Old
