Overview

ℹ️

HSC 1083 is a poorly populated, moderately dense object of high C3 quality. Its parallax locates it at a moderate distance, well above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
