Overview

ℹ️

Danks 1 is a rich, very dense object of 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, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.28 kpc) differs significantly from the median photometric distance (~3.80 kpc).

Note: This object shares a very small percentage of members with 2 later reported entries. See table with shared members information.

Distant Very high extinction Massive Very young
