Overview
OC 0689 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near 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.
â ī¸ Warning: This is very likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.
