Overview

ℹ️

Kronberger 12 is a poorly populated, very dense object of intermediate 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 parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~3.66 kpc) differs significantly from the median photometric distance (~1.89 kpc).

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