Overview
OC 0650 is a sparse, moderately dense object of very high C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~5.98 kpc) differs significantly from the median photometric distance (~4.28 kpc).
Note: This object shares a significant percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
