Overview

ℹ️

Collinder 396 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by low extinction. It is catalogued as a low-mass, old cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~5.11 kpc) differs significantly from the median photometric distance (~0.70 kpc).
