Overview

ℹ️

ESO 311 14 is a sparse, very loose object of 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 young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~6.44 kpc) differs significantly from the median photometric distance (~1.28 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 Young
