Overview

ℹ️

HSC 599 is a poorly populated, moderately dense object of low C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.
