Overview

ℹ️

Kronberger 57 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-rich, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~3.54 kpc) differs significantly from the median photometric distance (~2.43 kpc).

Relatively close High extinction Metal-rich Intermediate age
