Overview
OC 0007 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is poorly studied in the literature.
