Overview

ℹ️

HSC 2829 is a poorly populated, moderately dense object of low C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It was recently reported in the literature.

Close Moderate extinction Near-solar metallicity Very young
