Overview

ℹ️

Kronberger 28 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~4.09 kpc) differs significantly from the median photometric distance (~2.69 kpc).

Relatively close Moderate extinction Intermediate age
