Overview
ℹ️
NGC 7235 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above 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 age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Note: This object shares a moderate percentage of members with 3 later reported entries. See table with shared members information.

Distant Moderate extinction Massive Near-solar metallicity Very young
