Overview

ℹ️

Kronberger 73 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, metal-poor, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~7.41 kpc) differs significantly from the median photometric distance (~2.69 kpc).

Note: This object shares a significant percentage of members with a later reported entry. See table with shared members information.
