Overview
ℹī¸
NGC 6846 is a rich, very dense object of high C3 quality. Its parallax locates it at a very large* distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, metal-poor, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~12.41 kpc) differs significantly from the median photometric distance (~5.32 kpc).
