Overview

ℹ️

Stock 24 is a rich, very dense object of high 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 metallicity parameter (see Parameters). It is well-studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Young
