Overview
NGC 6357 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.
Note: This object shares a small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
