Overview
ℹī¸
NGC 6683 is a rich, loose object of very high C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a very metal-poor, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~3.50 kpc) differs significantly from the median photometric distance (~1.44 kpc).

Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.
