Overview

ℹ️

HSC 1445 is a sparse, very loose object of high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It was recently reported in the literature.

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.
