Overview

ℹ️

Kronberger 2 is a sparse, very dense object of high C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~1.65 kpc) differs significantly from the median photometric distance (~3.13 kpc).

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