Overview

ℹ️

NGC 6611 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close 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 age and mass parameters (see Parameters). It is very well-studied in the literature.

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

Relatively close Moderate extinction Massive Near-solar metallicity Very young
