Overview

ℹ️

UBC 224 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, very young cluster (see Parameters). It is poorly studied 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.
