Overview
OC 0470 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a very close distance, near the mid-plane, affected by low extinction. It is catalogued as a metal-rich, very young cluster, but with a large variance across recent sources for the absorption and metallicity parameters (see Parameters). It is poorly studied in the literature.
Note: This object shares a small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
