Overview

ℹ️

Kronberger 1 is a poorly populated, dense object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.

Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry, and a moderate percentage with at least one entry reported in the same catalogue. See table with shared members information.

Relatively close Moderate extinction Near-solar metallicity Young
