Overview

ℹ️

ESO 026 02 is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a large^* distance, well below the mid-plane, affected by low extinction. It is catalogued as a massive, very old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.46 kpc) differs significantly from the median photometric distance (~2.47 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.

Relatively close Low extinction Massive Very old
