Overview

ℹ️

ESO 561 05 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 low extinction. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.23 kpc) differs significantly from the median photometric distance (~2.77 kpc).

Relatively close Low extinction Old
