Overview
MCM 3 is a sparse, very loose object of low C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane. No fundamental parameter values are available for this object. It is rarely studied in the literature, with no articles listed in the last 21 years.
Note: This object shares a small percentage of members with 3 later reported entries. See table with shared members information.
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
