Overview
Danks 2 is a rich, very dense object of very high C3 quality. Its parallax locates it at a large* distance, near the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-rich, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.
(*): The parallax distance estimate (~7.17 kpc) differs significantly from the median photometric distance (~3.60 kpc).
Note: This object shares a very small percentage of members with 2 later reported entries. See table with shared members information.
