Overview

ℹ️

HSC 1129 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.
