Overview

ℹ️

NGC 6698 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 moderate extinction. It is catalogued as a massive, old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.41 kpc) differs significantly from the median photometric distance (~3.79 kpc).
