Overview
OC 0652 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the absorption, age, and metallicity parameters (see Parameters). It is poorly studied in the literature.
Note: This object shares a significant percentage of members with 2 later reported entries. See table with shared members information.
