Overview
OC 0027 is a moderately populated, very dense object of intermediate 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, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
â ī¸ 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.
