Overview

ℹ️

HSC 826 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.

Relatively close Moderate extinction Near-solar metallicity Intermediate age
