Overview

ℹ️

PHOC 2 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, young cluster (see Parameters). It is poorly studied in the literature.

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