Overview
ℹ️
NGC 6200 is a moderately populated, very dense 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 massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~2.88 kpc) differs significantly from the median photometric distance (~2.21 kpc).

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