Overview

ℹ️

HSC 1388 is a poorly populated, very dense object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (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.

Relatively close High extinction Near-solar metallicity Intermediate age
