Overview
OC 0588 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a close distance, above 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 parameter (see Parameters). It is rarely studied in the literature.
Note: This object shares a very small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
