Overview

ℹ️

ESO 165 09 is a sparse, 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 low-mass, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.54 kpc) differs significantly from the median photometric distance (~0.45 kpc).

Very close Low extinction Low mass Intermediate age
