Overview

ℹ️

NGC 6837 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, well below the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.05 kpc) differs significantly from the median photometric distance (~2.79 kpc).

Relatively close Low extinction Old
