Overview

ℹ️

Kronberger 84 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age 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.

(*): The parallax distance estimate (~4.73 kpc) differs significantly from the median photometric distance (~3.40 kpc).
