Overview

ℹ️

Basel 17 is a poorly populated, moderately dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is moderately studied in the literature.

Relatively close Low extinction Near-solar metallicity Young
