Overview

ℹ️

Hogg 6 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, 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 (~3.77 kpc) differs significantly from the median photometric distance (~1.60 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 Low mass Intermediate age
